I'm neutral on the whole combo idea. I like the idea of saving space, but I still find myself having more difficulty doing the combos in pvp over the separate buttons in PVE for some reason, but I can still work with it.

As a controller user, though, I wish everything could fit in 32 hotbar slots, that includes slots for teleport, return, mount, party finder, duty action 1, duty action 2 (I hope there is no 3), and limit break. That leaves 25 for job and role actions.
