I just hit 50 with my warrior got the first armor and got lucky in dropping ifrit's axe from 2nd run but here's my problem.

Yesterday i did my first run on CT ( i didnt have any experience on tanking there) i informed my party about it and yet no one explained on what i should do so i screwed up on behemoth by aggroing the boss unwillingly ( it was more like ninja-pull cuz i lagged and gone straight to the boss lol ) and got flamed by the whole alliance. No one really cared to tell me from my party what to do in this boss just "take a tower" nor they did in the previous ones so i was more than useless.

But here's my question, it seems like ALL tanks should make research on the raids/dungeons after 50 otherwise wipe is sure? Also, regarding CT every monday all robots gather for their items and don't give a damn about explaining the instance?

P.S: Anyone experienced lag issues on CT?
