It does seem cool, but looking at the card database (so possibly missing some newer sets?), of the 4 current helm/head slots, 2 are already warlock only. It doesn't feel this helps diversity of spell book development, rather just makes 2 of the other cards mostly redundant? I guess I don't really like/understand the mage specific spells anyway. They already have a cost for non specific school mages using them, why not let them be used? Most of the coolest cards seem to be mage specific. I guess in time as the card pool grows it wont matter, but atm it feels like a canalization of choice rather than a growing of diversity.
Well, well, well.
First, the 2 already existing helm can't be used in Academy, so that's the first reason of its existence.
Second, the fire helmet is pretty much useless for the curse warlock, it is more designed toward the fire warlock.
Third, the fear helmet is one of the original card, the game was new, designer less experimented, so the helmet ended up not being that good for its mana cost. So having a good cheap helmet is a natural thing.
Mage specific cards are meant to totally prevent other type of mages to use them to prevent overpowered combos.
I don't want to imagine a world with a Wizard using Barkskin... no... just no.
There is over 400 unique spells so far in the game. Having about 10-15 mage specific cards do not canalize choice.
