ice mage is a huge wasted potential.
the game has some tendency of making ice spells grant block. thing is there really isnt a lot of cards that utilize that block. at higher difficulties you already have a healer/tank, block by itself is of negligible use. The only mage card that turns block into damage, yellow/purple variant of the Winter Orb, sadly has vanish.
the Queen performs exceptionally well early on due to yellow variant of Ice Lance being reworked to do mind+ice damage, while also being 0 cost and vanish. With the +damage perk tree you can get a ton of damage out of this card. Now if only a character comes with 4 copies of said card and can craft 2 more.. you guessed it, that's the Queen. She later on becomes rather weak, as she doesn't really have a consistent source of damage, does not have reliable cost reduction, and ice spells being weak overall. the rate at which she stacks chill is actually slower than a elemental weapon Elementalist. I hate to say it, but from my playthrough, the Queen doesn't do as much total damage OR ice damage as the Elementalist, who is a free base-game starter hero, and that's even without picking Glass Cannon (+60%dmg for flat -25hp) as the latter's lv5 talent.
I'm not saying DLC heroes should be pay to win or smth. but the Queen brings so little to the table that I hardly want to pick her a 3rd time.
Well at least this time they had an acceptable price ¯\_(ツ)_/¯ A good step in the right direction if i may say.
