I'm still pretty new to the game, but I would consider myself a pretty good, well-rounded gamer who's had his share of competitive TCGs, minis and board games.
After picking up nearly everything for Mage Wars (don't have Druid vs. Necro yet), I wanted to play the Force Master because I think she looks the coolest. Sadly, after doing some in-depth research and class analysis, I'm a little confused of her purpose.
It seems that all the other classes in the game can function better than she does. When you compare her spell repertoire with respect to point cost, it seems that she's very unfocused and cost ineffective. Take the Wizard for example, a lot of the staple spells that people find essential are in the Arcane tree. It's no surprise why people consider the Water Mage to be extremely strong, capable of multiple styles of play and openers, access to cheap and plentiful Dispel/Dissolve/Teleport/Mage Wand, all while having access to any creature in the game for 1-2x.
The other classes also feature pretty decent abilities, but the main thing to take away from those classes is that they can take creatures. Creatures in their own school costs base, those outside costs 2x, and very rarely do they need to dabble in their weakest tree to take the 3x penalty. Why is it that the Force Master is the only class in the game that pays triple for all creature spells outside of the Mind school? It doesn't help that mind creatures are a complete flop with all things considered. Creature actions dictate the pace of the game a lot, and having a class with limited openers and predictable gameplay is just a little lackluster. I don't think the concept of solo play works very well in a game where multiple actions result in more dice rolled, and more dice equates to more damage while multiple creatures means more survivability.
If her purpose is to play control, I don't think she does a very good job at it. If it's about doing solo damage, I don't see it either (especially with the Bim-Shalla nerf). It's certainly not about supplying creatures, because she's pretty bad about that. A spell-slinger mage doesn't work either because you're going to run out of cards, and they have finite use/application. Aside from a few Grizzly teleport tricks, what is her actual win condition? What can she do that a Water Mage, or a good Priest, or good Beastmaster, can't do better?
