I just got to lvl 50 on my first tank (DRK) and I'm fairly comfortable in 4-player content. That being said, I haven't done any 8-player content because I'm not too sure what is expected of me in those. I've vaguely heard of tank swaps, tank busters, MT, OT. I haven't even attempted a Main Scenario roulette because of this, so I would like some help on how the role evolves at lvl 50. Thanks in advance for your help.
