So, im sure im not the only one that noticed this, but the global cooldown at 2.5 seconds is just too long. The combat is too slow, even with the abilities off the global. The Pace is way too slow.

I know the justification for this was so players would have more time to make their decisions, but this is a great underestimation of your player base abilities. Most of us have been playing MMO's for years now with global cooldowns of 1.5 seconds or less and a combat that flows is better than one that assumes you are too slow deciding what you need to do when you're going through your rotation for the gazilionth time.
Of course, i understand that things like the TP regen rate would have to be readjusted, maybe HP pools readjusted and that the skill speed stat is in the game. Sadly though, the skill speed stat doesnt do nearly enough to make a dent on this problem, besides not solving the issue to lower level players.
