And yeah, maybe everything nice from Tara does drop. But the place is 9 years old and 90% of the time is killed by an raidforce of AFKers. Clearly, you cannot just level to 220, farm collector for a week and be done. But it certainly speeds things up.
Honestly I think it is a step by FC to address the fact that population is terrible and a lot of things only get done with people multilogging. Although the whole thing is basically standard FC fodder - tank doc crat profit. with a crat the instance is easy, without...well those green bastards arent very nice ;p
Disclaimer: I been to collector 3 times and the best thing i got was a gph. and i already had an igph.
