The potency change isn't why I'm thinking nerf. IR no longer getting any bonus from Litany/Strategem, IR not lining up with TA windows since it's now 90 seconds and losing the flat damage buff on Zerk in favor of the Crit/DH hits doesn't seem so good. We'll see, since it will certainly be tested.
EDIT: It's 90 seconds, so every third IR will still hit, my mistake.
