When dps dont aoe should they just get kicked from the start?

[Niwashi]

If a tank is making big pulls and a DPS is single targeting on them, that's a lack of coordination between both players. It's as much the tank's responsibility to adjust pull sizes to suit the DPS's actions as it is the DPS's responsibility to adjust skill rotation to suit the tank's actions. If you're going to kick one of them for failing to coordinate that, then you should be kicking both, as they're equally at fault. The only exception would be dungeons where individual packs have lots of mobs and it's impossible to pull any smaller.

If you just don't want to bother even trying, well then I don't want you in my group.

If you don't want to be grouped with someone, that's your prerogative. But that's what the "Leave" feature is for. It's NOT what the "Kick" feature is for.
