A good friend of mine (VanilleFang of now permaban-infamy) enjoys poking fun at me in discord every time I complain about getting bads - I'm just told "You know what happens when you do things by yourself!

" but like... okay, yeah, fair enough.
It's also the age-old question when queuing for 24mans in particular; do I heal it for safety, dpsing it for speed/confidence in meeting the dps checks or tank it so that doing the former two doesn't earn me a (deadly) tankbuster to the face?
The game definitely needs to teach people a whole lot more. There are currently several threads going on just on the forums about this same topic.
Personally I feel like with the leaps they've made with having your AI companions perform mechanics (or not perform them, LOOKING AT YOU TATARU D: ) they should redo some of the job quest battles to actually teach you things and use them as gates. Healers actually needing to heal a party, tanks needing to maintain threat and dps having to at least oudtdps those AI xD
