I'll give it a shot, but it doesn't seem to be that amazing. I expected something a bit more interesting TBH.
FPS games are very tricky to get the "feel" right, so you need a few PC staples like dedicated servers and a lot of control customization. The fact that you can switch heroes on the fly seems really weird, the design seems like it would lend itself to locking yourself in for a whole match.
The art style is pretty terrible, it's very generic while hitting all the right notes, there's no "this is Blizzard". If somebody showed me the screenshots, I'd guess Firefall or some asian F2P shooter. I know bitching about female portrayal in games is the hip thing now, but literally every model is tits n ass in the same pose. You can do better Blizzard, this shit is so safe.
Unless this game is F2P, it's dead.
