I've tested this on the PzDF server too, here's the impressions:
Picking up grenades is neat, you usually end up blowing yourself but still a nice addition everyone was crying for.
Locational crew killing didn't work on PzDF server, so we switched to the Japanese one and it worked, I can't comment how well it did though.
New rounds for tanks is great, what is greater is the new loading system. It's really what was RO missing.
New tank entering/exiting, not too much change here. You have to enter the vehicles from certain locations and when you exit, you're on the top of the tank. You may think adding some delay. Please remove the tank turret MG shake as well
Thanks for "Voice commands in your head" thing, it was really bugging me off
(This didn't work on PzDF one too, voice commands were missing)
Machine guns, why did you mess with them? They're very uncontrollable and very inaccurate. Also, greatly reduced sway on the other weapons just mean that MG'ers won't live long in this mod. You should consider some tweaks.
View shake when a tank passes by, it's what I've always wanted but I think how you did in the mod is a bit funny
You should consider adding some blur along with shaking.
Custom skins/helmets, good. There was a bug on Arad though, spawn as Axis Tank Commander and your hat won't have the correct skin. It just shows the default UED texture.
That's all for now, pretty good mod
EDIT: One more thing, I LOVED the thing that when your tracks are out, you can still go around in circles!
