Hello there !

If it can help, i've discovered a bug (with some friends) on our favorite bladesman:
Sometimes, when we cast Alpha Strike on ennemies, the cooldown doesn't
appear in the skills bar. The spell seems ready, but is in fact still refreshing, and
cannot be used yet. Happened quite a lot of times now, so you may want to check it out.

Hope it helps, and thanks again for your great work !

yeah i've noticed this a lot lately too. if you wait a bit you'll be able to cast again and "should" show that it came off cooldown. good luck
