I found Ambra’s change to be really powerful. I think the boost in healing was warranted since it was quite weak before. And I like the idea of choosing between DPS Ambra with radiant halberd and Sunspot Ambra with melee attack heat use to be an interesting choice. I do think that both the heat use to reduce the cooldown and reducing the cooldown to 8 seconds might have been a bit much, I think one or the other would have worked better. I personally would prefer the using heat to reduce cooldown for the choices it gives.
Much more than that I think they need to do something about the character curve with Ambra, the difference between a level 1 Ambra and a level 15 Ambra with legendary is miles, even with the same skill and experience with her, her mutations and her legendary are that important and I think it’s a bit much.
I am disappointed with the changes on Kleese, he was one of my favorite characters and I wouldn’t even consider him a support anymore, he is a territorial tank with some minor group utility.
I do quite like the new UI though, and am mixed on the changes to the legendarys, some I really think the new secondary was helpful, and some I think made the item borderline unusable for the cost.
