Yea how it'd effect basing was definitely taken into consideration which was why we already slightly increased the hittimer within bases to give a little bit of breathing room when it isn't a 1v1 situation. Its already been increased for about a week now, you just would likely not have noticed it as it's around 0.3 which is roughly the lowest firerate for most of the higher tier guns post nerfs (with the exception of a few of the 9 damage perfect guns like mtar/mp7).

Yea hittimers will likely be adjusted on a few guns if they prove to be any better than they should be because of the additional damage (talking in terms of how it compares in its pre-buff hierarchy). Believe me I don't want instances where you get hit by 4 bullets at once and die instantly, so hittimers will probably start becoming a slightly more important stat, however I also don't want to over do it because I know how annoying it can be if the hit-timer is messing up your shots, so i'll probably aim for it to be around the firerate of the gun it's on.
As for BAR/PSG being used more, i'm not sure. You have to remember that whilst yea they can kill in 4 shots, guns like the GM4, M4a3, Metalstorm have significantly less freeze/ other beneficial stats over the BAR/PSG which will keep them relevant still. Almost all guns will be killing faster, but it shouldn't be any different to how it is now hierarchy wise, if it is then there will be a minor tweak to that gun
