Imo, 343 has done a great job so far on Halo 5. I like:
-Sprints implitation
-Fair and equal starts
-Map design and power weapons
-The graphics
Things that need to be changed.
-Some balancing issues mainly including the AR’s range.
-Spartan models, maybe something similar to Reach’s?
Also it looks like this awesome game is geared for e sports. Just dont forget all of us love BTB and I hope you guys don’t forget about that in the final release! And congratulations, im really enjoying this game.
