Alright, here's the things that jumped at me like a sore eye within the 15 first minutes:
The voice acting removal, it's not too quiet, i enjoyed the voices, now the game is just too quiet because it has no background ambient sounds, i'd suggest letting the voices in and give the players the option to make it on/off, some people may like the silence, i personally enjoyed the voices more.
The time delay: Overwatch can be sped up by 2 or 3 times, it's still too slow before it goes for the next turn.
Starting team members: I want to be able to customize them, i hope this feature will be brought back, i don't want to start with random jacks that i have no love for.
Starting merc: Would it be possible to just not hire a merc at the start? I want to keep the 50 credit.
Inventory scrolling: When scrolling down or up with the mouse wheel, it's waaaaaaaaay tooo slow.
