, I quickly loose aggro on the strong elite because aggro generation in SWTOR is not like other MMO's where tanks can hit a mob once and never loose aggro.
Which btw is a point of note for DPS players. Give the tank half a chance to get and hold the aggro. Some boss fights the tank specifically CANNOT keep on building aggro due to the fight mechanic. (e.g. the big rakghould in Kaon which does knockbacks and must be kited from barrel to barrel).
Despite this, I've seen DPS players carry on hitting from range as hard as they can, followed shortly by complaints that the tank isn't doing their job. It's not a bloody race, chill out on the DPS to let the tank well... tank!
