Well I didn't think it was that bad tbh. I only played a few games with the British guy and a LMG. I think it felt better than others as I didn't run around like I usually do.
The War mode was great to start with, but we had a group of us the next round and I think most got disinterested pretty quickly. A tiny bit of lag but overall i'd say it was nice to experience it.
It's been said before by a few of you but I think the main issue with people not liking this is that most have just grown out of the game so you haven't got the patience like you used to. Might try it again tonight for a few more War rounds. Its by far the best game mode. Oh, it did feel like we were playing Rainbow Six mixed with Overwatch moving the payload
