So…she has the biggest defense debuff outside of a single HOTM that’s not available any longer (Athena). And 44% debuff vs 34% from the 4 star crew (Gormek, Grimm, Tibertus) is a big difference damage-wise for titan hits. Her slow speed isn’t so relevant for titan hits since you can use mana potions.
And for raids, an AOE -44% defense debuff is almost game over. I can tell you from an offensive raiding perspective, Azlar and Isarnia are the 2 AOE heroes I least want to get hit by. Give me Justice any day of the week.
I have her and Richard on my alt account and if I don’t get Alaise in my single 10x pull tomorrow, I will totally take Isarnia to tier 4 and not think twice.
