Well you are certainly right with a few things, however like i explained the timers work well enough in other mmo's like WoW, so i fail to see why it shouldnt work in SWTOR as well. And with well enough i mean it gives a rough estimation but i never experienced it giving a totally wrong estimated time. For example in the newest Raid in WoW, the last 2 wings normally have a long queue for dps (arround 45 mins) but i never had to wait more then 60, and in alot of cases it was exactly arround the estimated time.
