Take the next stuff as constructive criticism. Much of it is stuff I just don't like in games, others might so much of the next is purely opinion:
Why can you see all the players on your map... GPS?
Can be disabled in the server settings
The walking sounds like a bunch of catapillers munching on leaves, amplified of course. Just a comment, if anyone has been in the woods in the summer at night they know what I mean (or its their droppings hitting the leaves on the way down )
The strange sprinting sound is a bug, will be fixed
Running looks too fast, no loss of stamina? At some points (one at 31:05) players seem to be sprinting faster than I've seen most dogs run.
There is no stamina, but long and fast running has a huge effect on your aiming. Moreover I don't think the running is too fast.
3rd person view, I really don't like as it seems like cheating. As Sidestrafe said, its kinda 'cheap'
Can be disabled in the server settings
Too much info and HUD on the screen.
I think this can partly be disabled in the server settings
On the second map, lots of driving. Are there players just racing in jeeps to the cap points, cap and then move on? Seems more like a tank driving sim.
Seriously? There are lots of vehicles and cars in this game and you are free to use it or not ... if you prefer to walk to the objectives, then you're free to do so
Seems more points awarded for accidents (destroyed by accident)? In other words, more vehicle destruction by accidents than actual combat.
I am not sure about this one, because I didn't really pay attention to it (maybe the system is a little buggy, idk), all I remember is that I destroyed my Fw190 right after the beginning of the second map, because I flew in the spawn protected area of the enemy
Too many players running and ramboing with mgs, looks hokey.
I can't agree on this one, there were not many MGs running around and "ramboing with MGs" like it is impossible in Ro2, the recoil of the MGs is way too high to do so.
Players teleporting into vehicles at one point escaping fire because of it.
I agree on this one, but it's really a big deal to my mind.
Can any player just grab any weapon out of spawn? Can any player just drive any vehicle? I personally don't like the idea of no classes.
There are classes. More details about the several multiplayer modes will probably follow shortly before or after the release.
IS2 turret moves to fast (with mouse?) seems very unrealistic.
I don't know how fast the turret of an IS-2 can rotate, so I can't say anything about this one.
Big maps, while I like, just need a lot more players than what is represented in the video. I mean there should be hundreds. Because of this it seems there is very little combat for the time spent on the maps.
The multiplayer footage by SideStrafe was recorded during a press event with only ~20-25 players, the engine is capable of handling much bigger player counts, so don't worry on this one. Furthermore there are lots of missions for different amounts of players, from very small and fast paced to very big and slow paced.
