Guild Wars 2

knowing that the necro staff is THE most powerful weapon for the necro, sometimes the game for that matter, they did that for balance reasons.
not every profession is a spam-a-lot like the thief, you need long recharges for skills that are more powerful then your average fast skill.
in some cases i can understand what you mean tho, why does it take that long to reload a summon like hounds of balthazar or the mist wolf, a recharge of 40-60 is enough giving that it takes 30 seconds for it to die and it mostly die in battle anyway. (it’s an elite, make it at such power)

in allot of cases it’s a matter of balance, in some cases they do need to lower the cooldown to make the skill more useful then it’s current uselessness.

Elementalist is the best class in this respect, I can imagine with some classes you are just standing around auto attacking because everything is on cooldown, for whats supposed to be a ‘fast paced’ combat system, its often quite relaxed to the point where you are playing on ‘auto pilot’.
