Sorry mate, you sound too much like a permanent rant. You also seem to ALWAYS forget regen % on your calculations:
Operatives regen at 5% total energy per second, 3% per second in medium zone, 2% in lowest regen tier. Without the buff.
Socerers regen at 8/500 = 1.6% per second. Without buffs. Even less if they have 600 Force.
What is exactly your point?
The "forget regen % on your calculations" IS his point.
Do you really think anyone cares how long it takes each healer to fill their bar back up?
Or do we care how long it takes each healer to be able to afford a cast?
