JA-lock is a huge frustration. I really shouldn't have to build in gearswaps just to blink my character when I use JAs. I enjoy all the animations that came with subbing Scholar, but I absolutely hated getting locked in place. It's the kind of thing that can get you killed, so now I just blink every time I use those JAs and I don't get to see what they look like anymore. This is poor design and fixing it should be pretty high on the to do list.
I'm probably going to have to do the same thing for Corsair and I'm not looking forward to that since the animations tell me what I've rolled well before it shows up in my chat log.
