I've got the same issue, I used to think those abilities where awsome when I first got them, but then I found out they're extremely hard to use in party when there's a big mess on the screan/chat log.

I think the main issue is that those skills are always active on the action bar once you get enough TP, they should be active only when you're allowed to use them, also because most of them can be executed on a really short amount of time and often even if I notice I'm allowed to use them I can't do it in time due to lag or stamina.
