Why didn't 4th Job AoE's get a cooldown?

When 4th was confirmed to come out in a month's time, suddenly TONS of people reappeared and TONS of new Priests starting appearing due to the knowledge of how great Genesis was going to be.

around that time, i saw more crusaders and bowmasters than priests lol.

and i dont see why people dont complain about BMs and NLs being "omfggg theyre overpowered at bosses. thats totally imbalanced" but rather say that archmages being overpowered on the training field. it seems like its easier to place the imbalance blame on the smaller group of people; inexperienced zrunners at zak STILL do not allow archmages to use ultimates on the arms because it 'lags' when everybody knows that can be fixed by casting ultimates before zak is summoned so you dont lag.

and here people are saying archmages are overpowered on the training field. if you job is a thief or bowman and you train slow, hating magicians for getting exp 2 and 3 times faster than you, if you cant beat them, join them. ie party them.
