So I've been seeing a lot of people saying they are having trouble keeping track of when Air Anchor and Drill come off CD. And I was sat wondering why I don't have this problem with Gnashing Fang on GNB, but do fall into it with MCH, and I think its because of the flashing lines around Gnashing Fang when you have powder.
I think Drill and Air anchor should get the flashing "combo" line around their icon when they are off CD to draw your eyes to them better, as well as any other skill like them.
