tank/healer – you won’t find a better combination, they know exactly how the other works and are the best at keeping the whole group alive
tank/tank – they have the guild or group of friends divided and everything turns into a popularity contest. even if one of them accepts their fate as subtank the bitter resentment is a ticking bomb that one day will go off. good luck.
tank/dps – the human representation of the “hoe dont do it” *does it* “oh my god” meme
healer/healer – would be like tank/tank if it weren’t because they’re probably the most stable relationship in the world with all that saintly patience. bless
healer/dps – snarky pieces of shit
dps/dps – god no
