The dumb modders who can't put the bloody effort in to play normally like everyone else and keep ruining the gameplay for all of us. That lobby i was in, this guy used 3 EMP's in less than 20 kills and then this AC-130 rapid fire started, and then a guy on my team did the same thing with it just after his ended. Just about every modder you see, they're always the idiot ones – using godmode, aimbot, being invisible so you can't see them & getting themselves free kills, resetting everyones stats, ranks, classes and titles & emblems – making you have to start all over again. Even though i find it nice from the good ones who unlock everything for you and max out your rank, some players don't exactly like having that coz they mainly prefer leveling up the normal way by completing challenges and getting kills.
If any of these iconic cods got remastered such as BO1, BO2, MW2 & 3 World At War etc and changed to latest gen console versions, we wouldn't have to deal with this anymore.
