The best shotguns for me were on Cod 4. Barely anyone used them. But they were usable, and depending on the skill of the player, you could do well with them. And they were close range.
IMO on blops2 they are op, whilst a shotgun irl provides very long range, as far as games go, it just doesnt work well...
To me its like no scoping, except you spray 20-30 shots which 1h1k, instead of the one you get with a sniper.
It's just for lazy people who can't be bothered to actually work for a kill.
It doesn't take me twenty to thirty shots to kill one guy, just the whole team several times before I die (most of them one hit kills).
I don't think they are are overpowered and even if they are what is to stop another person from picking up your weapon when you die...
The guns and other weapons are fine in my opinion... the only thing wrong with this game, and its a big thing, is that the Host is the winnner 90% of the time... that is f(&$in annoying. I just get over it and wait until I am host an have my fun otherwise it turns into:
Shoot the enemy from 3 feet, dead on headshot, and you miss 50% of the time...
This is in my own opinion how a person goes from 42 kills and 3 deaths to 3 kills and 20 deaths in one "Host Migration"... BS!!!!!!!!!!
