Treyarch buggered up Mercenary so I have to play TDM. I don't waste my time playing any other gamemode as they're infested with groups.
Naturally I oppose your crying about people quitting your pubstomping attempts. Here's my auto-quit checklist:
-If it's an existing lobby note player grouping by score when new teams are selected for next match. If high scoring players are placed in same team repeatedly as players leave lobby and new teams are selected, autoquit..
-more than 2 players with same clan name? autoquit.
-players with mics all grouped together vs. non-mics, autoquit.
-note top few players in lobby, when teams are selected if game puts top 3players on same team, autoquit.
-nuketown, autoquit.
-join game in progress, hit X, view scoreboard, team down by more than 10 points, autoquit.
-join game in progress, hit X, see same clan tags, autoquit.
-more than one group of split screeners in lobby, autoquit
-join lobby and am in bottom quarter of player SPM (last 3 places), autoquit.
-game starts and it becomes evident within first 15 kills of the match that the other team is working as a grouped team with some sort of co-ordination, autoquit.
I don't autoquit any other map except nuketown, even though Aftermath is just round after round of a clusterF*%$ in that room above the elevator shaft and the rest of the map is ignored. Ditto Drone and that machinery room and helicopter pad. Hijacked gets on my nerves if I play it more than once every half hour but I stick with it.
I think that pretty much covers it. I maintain a 2+ KD playing 100% solo TDM this way. Nobody in my country plays BO2 so I have to play in US lobbies which means I'm at a mandatory 0.5-1 sec disadvantage 24/7.
I have to play choose what lobbies I play in very carefully and don't have time for your pubstomping with all your little buddies BS. I'd play Mercenary and stay in pretty much the first lobby I joined but Treyarch force this MLG crap onto me by cramming Mercenary with game modes nobody enjoys, so I have no choice.
I trashed my SPM trying to play mercenary for a few months when BO2 first came out. Eventually just gave up and have stuck with TDM using above lobby quit conditions as above.
In MW3 I played Mercenary exclusively and rarely would quit a lobby I was put into. Ditto MW2.
