Well my rl friends started playing silk road europe, so we are planing make a good party(well balanced). I wont ask whats the best combo for a party, since its pretty much obvious(tank/healer/dps)

.
What i'm concerned is about tankage(i have a prot war on world of warcraft), so i want to know how is tanking here? There is things like threat? Or just about taunting and minimizing the income dmg?Can some1 steal my aggro by doing dmg or healing?
Thanks
