I thought it was fairly well balanced, even if it had me staring more at my global cooldown indicator than at the thing I was killing.
If that strikes you as kinda strange/fishy as far as "gameplay" goes then you would be perfectly right. (Get out while you still can? heh
I don't use words like "simplistic" or "reptitive" lightly when talking about MMO gameplay... and cooldown based skill/hotkey gameplay is exceptional on both accounts.
Matter of fact... most of the combat in mainstream MMOs can played just fine by looking almost exclusively at your skillbar, the healthbars (of your target and your group) and the minimap.
This actually gets worse in the MMOs that feature large raids for bossfights... as the huge majority of participants will either simply hit their "assist button" to target the same mob their raid leader or "main assist" is on and then commence to do their cooldown based "DPS rotation" (i.e. smack the same 2-4 keys over ... and over... and over again until the mob dies, then hit assist again, rinse and repeat.) while healers either do their "heal rotation" on the main tank or play the healthbar whackamole game when "spot healing". The only interruption to that monotony may come from some cue/pop up (possibly from an UI addon) that will tell you "oh noes Boss will do scary attack in x seconds, better move to spot y".
All the excitement of a military drill exercise... i.e. leave your brain at the door. That's about it. And yeah, you will get yelled at just as much if you fail to jump when you get told to jump.
