It's probably a silly question but how important is the acc cap?
I'm MTanking Turn 4 in full myth (I have coil drops but War AF looks so much better) with 450 acc and I have no issue with enmity. I'm sure my DPS contribution could be higher but we're still doing fine clearing DPS checks.
My point is the acc doesn't feel to me as a true requirement for a Tank and I'm concerns about people not getting into Coil because of the acc cap.
I'm currently crafting myself a full set of 2 stars accessories which will put me at 480 in full myth gear but I'm really doing that as a personal achievement as I want a good OT build as well.
