Only time I get upset when dps or heals pull extra mobs are when I have a brd/mch and a melee and if they pull more when i have casters etc they have a death wish because I've already pulled as much as i know my Cd's can handle. I like pulling big and getting in and out as much as the next guy but I feel no need to get bashed in the face for a solid minute and a half when I could be chain pulling instead. If I have one our more caster or brd/mch with a caster I'll pull accordingly. Not saying 2 melee can't wreck a big set of mobs but getting them in random df groups is rare and not something I care to test.
