I wasn’t trying to make an apples-to-apples comparison, just saying that there are other, arguably better, passive mana gen traits on Mythics who aren’t A-Tier. I think Mistralus and Aurora are pretty comparable, both good-to-great support Mythics who have trouble carrying a team by themselves.
Next week is a Dragon’s Claw event. We discussed the Legendary extensively here. It suffers from many of the problems Elemaugrim has - dependent on other troops for a status effect, random gem creation that gets more unreliable the fewer troops the opponent has, and merely ok damage for all that startup cost. Not good.
The glory troop, Sylfrostenath, unfortunately offers little to make up for the mediocrity of the Legendary. It looks like they were trying to make a lesser version of Borealis, with the skull reduction and the inflicting of freeze on cast. At least Sylfrostenath damages all enemies with its spell, but the skull reduction is mediocre and it doesn’t do enhanced damage to frozen troops, meaning it’s missing the good parts of Borealis. Oh well.
