Ok here's a few reasons I dislike playing with people younger than around 18 (I've met a few 15/16 y/o's that are good to play with tbf). 1. I've generally found that older players, not only on Destiny, have a higher skill level and are much less prone to repeating the same mistakes. 2. The screaming/raging. Oh my word that is annoying. Joining a game where someone dies and goes absolutely ape s*** at the game is one of them most infuriating things about gaming in general. Just chill. 3. The racist/homophobic tendencies you see in kids is unbelievable. The amount of times I hear someone call another person n***** or f***** or something along those lines is unreal. 4. General inability/unwillingness to listen. Tried to do a few raids with kids who hadn't done it before, generally they'll do their own thing and just ignore what you say. I say: Let me take the relic. They instantly pick it up, die then we restart, I try to explain to them how to use it so they know for future reference they ignore me and do whatever. You get the gist. I could give a lot more reasons but I've realised I've rambled on for far too long. So yeah, a few reasons there. EDIT: I realise it hasn't bleeped out my swears so I've done it for you.
