Everything looks great on the newest Dev release. I think I may be confusing how the action button fadeout is designed to work though.
Using the current Dev version, I cast a spell on the mob that causes a debuff. The debuff timers kick in and at the same time the buttons fades out. Looks great by the way, and the timer is real easy to read that way to
. With the debuff still on the mob, the spell's cast cooldown runs out and I am able to cast it again, even though the debuff is still on the mob. The button stays faded out though. Is that how it's designed? Or am I confused, lol.
