I don't consider weapon balancing and tweaking to be a massive change honestly. I didn't really have any issue with the game other than some lag and "netcode" issues, if that really is the source of the problem. I felt the M8A7 was a bit too powerful, but other than that I don't see anything to fix. Sure they could get rid of some "head glitch" areas and try to change the maps to ensure wall running gives players more of an advantage over camping players but I don't really see that happening.
