what is toxic anyway? people throw it around so much it became a pretty pointless word. nowadays its more akin to 'i dont like it'.
am i toxic? i guess you could call cynicism toxic. doesnt mean its wrong though.
quite some people dont play healer or tank to avoid responsibility. so they play dps. but dps do have responsibilities. even in casual content. its just that people first blame tank or healer and not the lack of dmg, because how could it ever be a dps problem? only evil people critisize that... blaming the healer is alright though. but dps does play a big role in surviving thrash pulls.
and of course selfheal and mitigation are also responsibilities.
