How about just giving us unlimited action slots like in every other MMO out there? And how about we get to bind those slots to whatever keys we wish?

That way we'd be able to actually see the cooldowns on all abilities at once and we'd be able to put items and macros into the bars instead of unnecessarily having whole separate systems for them.

Sure, you can't exactly play WoW with a game pad, but for those who insist on using pads even though it's not necessary even for future PS3 players, how about making the current UI available as an alternative? Sure, they handicap themselves when using it but at least it's optional instead of forced on everyone.
