Remove personal statistics if you are reluctant to remove statistics as a whole. But if you ask me, I'd say remove statistics as whole. Statistics will make CM feel like some competitive game as though we needed more of that.
Rounds end too quickly these days that you don't really have time to do any real RP. I can remember waiting an hour and a half in FOB talking to fellow marines like "Dude, wonder how's the front? It's dark" or have time to take coffee in CIC. You can't even, as CIC role, get marines to stall the game too cause xenos sometimes like to push out trying to get an advantage in the game and getting slaughtered or actually win. You can't blame xenos for that cause they start outnumbered 3 or 4 to one.
Another thing is probably the game does go stale cause as you play more normal rounds you get bored cause it's the same thing over and over. That's where we get ebents. And I seriously think people should stop complaining about ebents whether they are good or bad. It's a nice quirk to change the flow of the game. The point of ebent is to make rounds interesting from normal flows. Just adapt. Even if it is unfair to one side. I remember running straight at 4 ravengers and 1 abom in Big Red and was in for a surprise as a marine. Was a good joke, and it's a 2D spess man gaaame. You won't get to Global Elite by soloing the hive. You get no cash winning. So why get salty about a bad surprise event where suddenly xenos get insane stuff. Don't you people have fun? It's called an ebent for a reason.
There are a few gameplay issues that makes RP difficult. Take shipside roles for instance, Req, CIC and Medbay are the busiest dept in the game. The only goons that can RP around and do stuffs are Engineering, CL and Research Depts. You literally have no time to RP in medbay since you have to mass produce chems/meds for medics and have to be in surgery for all sorts of agony that keeps on coming. And they do keep on coming. You sometimes can get 8 critically wounded on board and you have only 6 slots to fix them, including Autodoc. By the time you are done, depending on the PO, you get the next wave in. Don't forget you have medevac guys as well.

You have to take into consideration for the people who don't have mic and also the bandwidth needed to stream them voices.
