The Remington is in no way OP. I have yet to see one shred of evidence that it is so, other than instances of lag distorting what people see, or having a good game with it on Nuketown. However, standing against the argument is the statistical fact that it is the worst shotgun in CoD history. 50 damage per pellet means diddly squat when its got less range than any other shotty. You take the R870, I'll take MW2's Spas-12 ANY day. If you accept THAT dance, you'll see how pathetic the R870 truly is.
the Spaz from Mw2 was just... wrong. That shotgun puts any shotgun in this game to shame with the ability to OHK at range.
For me the theres a few simple things they can remove and fix in this game to make it a lot better.. Like removing tactical insertions for example. It would remove spawn camping ***** snipers and fake feeders. Fix the problem with Toughness, that would remove the unblanceness within the game right now. etc etc
