I say just practice and play how you want, it will come with experience. Most people on here are much more hardcore than the average player. I've never had issues and have completed all of alex several times. I have no interest in being a DPS so seeing a MNK take damage I'd have zero way of knowing or caring that they did it on purpose to get out some kind of combo vs just being lazy. The buffs on the party list are so small and playing PS4 it's not like you have a mouse to easily hover over one to see what each DPS currently has on the go. It's very different playing with a static or a group of good players where things like that make sense. But for most people that just do DF, you get a huge mix. Sometimes good people sometimes bad, you just adapt.
