I've come to believe that the Warlock is the weakest Mage and I was wondering what everyone elses thoughts were on this. I think that the Beastmaster, Wizard and Priestess are all pretty close to being equal, with the Wizard having a possible edge, but the Warlock seems behind the curve. Below I will list out why I think this is.
The Warlock's abilities
1. Bloodreaper: In my opinion, this is a weaker version of the Beastmaster's Pet. Bloodthirsty is good, but requires a wounded opponent to function and also can force the Bloodreaper to not have a choice in what it attacks. The Beastmaster's Pet get's flat bonuses that are always "on" and always effective. In addition, paying life to summon the Bloodreaper (which you do not get back if it dies) is a much steeper cost than what the Beastmaster pays in mana for its Pet (IMO). Yes, saving mana is good, but the loss of life is very costly as it is helping your opponent win the game. I've seen a Beastmaster make multiple creatures his Pet in the course of a single game, but making more than one Bloodreaper is very painful (excuse the pun).
2. Curseweaving: This is a decent ability, but I think it compares poorly to the other Mage's core abilities. The other mages tend to use their abilities very often and they seem to have a much larger impact on the game. The Priestess's ability to gain life and remove status conditions is very good and will be used often. The Wizard's Voltaric Sheild is very good and will save you a ton of grief if used correctly. The Beastmaster's ability to quick summon level 1 animals is really, really good.
Curseweaving on the other hand is only ok. It probably won't be used every turn, or even every other turn and is dependent on your opponents build. If your opponent is playing a self-buffing beat-down style build that either doesn't run creatures, or very few of them, Curseweaving is essentially useless. No other Mage has an ability that can be basically neutralized like that. While putting curses back into your book allows you to run less curses (giving you freedom to run other stuff), it just doesn't seem to hold up to the other Mage's abilities.
Battle Skill: +1 to melee is a solid ability and is used often, no real complaints on this one.
Other factors: One thing the Warlock has that is a clear advantage is being trained in two schools. That can't be overlooked. Only the Wizard has something similar (although the Wizard's is better). However, I think that this bonus is counteracted by two other drawbacks. The first is only have 9 channeling. That hurts. The second is paying triple for Holy spells. While most of the other mages have a similar drawback, the penalty against Holy spells is especially painful due to the fact that it costs a lot to include any Healing spells. Lastly, the Warlock does have one of the higher starting Life totals, which is nice, but if he uses his Bloodreaper ability that kind of counteracts that benefit.
The Warlock's Support Cards
Lash of Hellfire: This is a great card, no complaints.
Ring of Curses: Standard cost reduction ring that each Mage has. Solid card, but I don't think it's as versatile as the Wizard's ring or the Priestess's.
Moloch's Torment: This is a good card and can be very effective, especially when combined with something like Ghoul Rot.
Helm of Fear: Decent card...if you roll well. The last time I played this card I failed 9 out of 9 rolls...ugh. Basically this card is hit or miss. When it works, it's great, when it doesn't, it's a huge mana sink.
Demonhide Armor: Don't like this card much. You're much better off with one of the armors that have some sort of elemental protection. The damage barrier on this is pretty weak, and you'd be better served with a Circle of Lightning if that's what your looking for.
Pentagram: Worst spawnpoint IMO. The requirement that it only gains extra mana from damaging opposing creatures is much worse than the Priestess's temple and (especially) the Wizard's Gate to Voltari (which is the best spawnpoint). Once again, this ability is dependent on your opponent's build. If your opponent is playing few, or no, creatures, gaining extra mana is going to be difficult. It's Ethereal trait is not enough of a benefit to justify the harsher requirements of mana generation.
Gate to Hell: I really want to like this card...but I'm struggling. It's soooo expensive for what it does. Yes, the +1 to melee for all demons is nice and adds up, but 12 mana is an awful lot to pay to get it (compare it with the Beastmaster's conjurations that buff animals). The ability to open the gate seems so good, but is also very expensive (another 12 mana). It can hit a lot of stuff, but it also hits your stuff (obviously you can build in fire protection/immunity to hurt yourself less). I dislike that it doesn't hit objects (just creatures) and that it doesn't hit fliers. Fliers are very big in our games, so that means a lot of stuff is going to not get hit by this. The one time I opened the Gate, it wasn't worth the massive amount of mana I spent to do it.
Sacrificial Altar: This card isn't terrible, but it's not really good either, and it has it's uses at certain times. You're killing off your own creatures for only a moderate bonus. If you kill off a Firebrand Imp (which cost you 5 mana to play) you gain a measly +1 bonus. Sure, you can kill off something like a Darkpact Slayer for a +3, but those are expensive. Obviously the best use is right when the creature is on the verge of death, but that can be difficult to time. Overall, it's a situational card that can be expensive to use. I don't think it's a terrible card, just not great. Compare this to the Hand of Bim-Shalla which does what it does for free and is much more flexible.
Goran (the Lycanthrope): I haven't gotten this creature into play yet, but it seems decent. Solid overall stats. I wish it had Regenerate though (because it's, you know, a werewolf...). Seems like a good creature, but I need to get it into play to test it.
So, overall, I think the Warlock's core abilities and support cards (barring a few exceptions as noted above) are weaker than the other mages. Warlock was going to be my "main" mage, because I loved the theme and flavor, but after playing a few games, I think the Wizard is probably the one I will play the most.
