Lagspikes which suddenly temporarily dc me from the game for up to 5 seconds at a time, every minute. Having a fun time, suddenly I see an entire enemy squad moonwalking past me, sigh and wait for the connection to reload. When it does, I'm dead to some random guy because I cannot physically do anything.
Quite a good list, agreed on most points except for the Decimator, I don't quite think it's universally better than default dumbfires. I consider myself pretty good with ballistic weapons, Flak Cannon was my favorite in Unreal Tournament, but even then I prefer default dumbfires to the deci because with deci I barely hit half of shots I would hit with the default. And I don't agree with "just aim higher" part. What if the target does that stuff we all tend to at some point in life or another - MOVE? But I guess that comes from using a dumbfire where a lock-on would work just as well, and only against vehicles. Against MAXes deci is a no brainer unless they're like super far. I'd like to add Full Auto shotguns to that list. I have some experience with all of the shotguns, and I haven't quite found anything in semi auto / PA shotguns that would make me choose them over a full auto when I need a shotgun to use as a shotgun - a weapon for unquestionable CQC dominance. As far as shotguns go, full auto is the best one by far. Whatever it loses in range, it gains twofold in firepower.
