I just looked at the ones you suggested and all would be affinity friendly. Good call on that. Now which would be best is the question? Skraank's A2: Attacks 1 enemy 2 times. Heals this Champion by 15% of their MAX HP on each critical hit. Wondering if that may throw off the stun attack possibly. Looks like to me Rowan would be the best pick of the 3 but I may be missing something. Rowan by the calculator after building the rest of the team the highest hp I am going to get to is 29,000. My pain keeper is sitting at 36,000. Again a big thanks to all of you for what you do.
I would go Rowan. Gonna be fairly easy to build and is a champ I think we want to have around at 60 too. We'll just pile poisons and that damage in there.
I was looking at Skraank too but that kit looks troublesome for tuning purposes.
Edit: missed your earlier reply about Skraank, sorry
