You are a random player, the dps are random players.
I dont know you or anyone else in the group.
Ive seen DPS with 6k HP doing shit dmg on tank n spank bosses.

Im not going to run around with 50 adds and die, because i trusted a bunch of random baddies. (I never did it, so dont bother calling me bad.)
This shit is just as cool as skipping the one mob pack in Temple, which 90% of time, does not work with PUGs.

There is no need to change, you should just stop forcing other players to do something, they are not interested in.
