I wouldn't use it for anything but healing...However for healing it is great. I was using two different ones...One for ops and one for dailies, but that just gets confusing. All my heals are in one place along with my defensive cooldowns and my in cobat revive. All my attacks and stealth are below that. Speeder/travel have their place and so does vanity stuff. So even if it isn't a ability I use often, I still have a general idea where it is located.
The only real pain is moving around on ledges an stuff, but how often do I really jump around with a full Ops group.
