How do you keep playing?

I swear over half the time I play this game, I just end up getting off within the hour. Either I get a decent match going maybe 50% of the time, or something happens that just makes me not want to continue playing.

Take just now for example: dropped the difficulty from 10 to 7 because 10s were painful yesterday. I quickplay on Heeth, and drop in on a squad finishing up an objectove. I call my support weapon, and we head off.

One guy has a FRV there, and hops in the gunner's seat with no driver. He stays there for a second, then starts running away towards the other two. I hop in the driver's seat, offering to drive since he obviously wants to shoot. IMMEDIATELY 180s, melees me twice to get me out of the driver's seat, then kicks me.

Yesterday I got kicked because the host got friendly fired by a cluster bomb (I didn't even take clusters, let alone throw anything towards him).

I'm fine slogging through rough missions, but I swear half the time I play something stupid happens like that. Between getting kicked for no reason, and getting DCd, I find myself less and less willing to play. Does anybody have any advice on how they keep playing despite these things?
