Alright so after spending around 20 minutes on .39.5, I probably won't be using .37 again except only for league events. Here's why:
-The game is brighter than 0.37 because of optimized materials (don't believe me? try it.)
-Really nice HUD (http://puu.sh/b2rjL/2f13ce371d.png)
-The ROR character is swagging (http://puu.sh/b2rmh/37fdaebca5.png)
-Better FPS (I went from 43fps in .37 maxed out to 73 in .39 maxed out)
-Physics stay the same like .37
-Nicer menus
-More multiplayer servers
Overall, I think we should really really really consider switching to .39.5 because its amazing. I don't see how its buggy because its not and if you don't believe me, download it yourself and try it out. I for one will probably never use .37 again except for league events now.
Also seriously LOOK AT THIS
Tell me that face doesn't make you want to switch over.
EDIT: Just got my server to work, so that means league events could work.
