Negatives:
Movement speed: Why? It's almost comically fast.
"Weapon balancing": Big Team had pretty much devolved into shooting at each other with DMRs from opposing sides of the maps. The only change is that you can now use different long range weapons instead of the DMR. ZZZZzzz. And now I have to relearn aiming with precision weapons because of the movement speed.
Weapon placement/spawning: Broken already. Slayer Pro on Haven, all 4 players on the same team had the sword. Infinity Slayer on Adrift, same but with the needler.

Positives:
AR is extremely deadly.
SAW is now a power weapon, lethal from much longer distances.

Overall: given the time they had, this should be much better. Certainly not good enough to help the player base.
