The fact that your SU-85s have to be in position before an engagement, and cannot rush over to help your ally, adds tactics and micro. That is a good thing, not a bad thing.
I am pretty sure you are quite good 1v1 player, so I would love to hear your suggestion.
How exactly does it add to micro and tactics if you are not able to reposition your force to engage enemy effectively.
Watching your teamate getting wiped of the map by 2 players, while other 2 enemy players are waiting in readiness for you to leave your 'position of engagement' so they can attack you and flank you on the move with bunch of Panthers/P4's and PG spam?
If you move you are dead, if you don't move you will be dead as soon as your teamate is done and dusted. If you are player that is on far side of the map and there is no one facing you, you are to far away to do anything and only thing you can achieve is again, be caught on the move out of effective fighting formation with units you have.
If you go and cap empty part of the map, you don't achieve anything. You don't decrease enemy pop cap, nor you significantly decrease their resources. At this point, If you are German you don't really care about VP, fuel or ammo. You are going for a kill, wiping one players after other, because you broke the flank and can easily swarm enemies from all sides, flank, infiltrate, etc.
The only tactic and micro there is if I play as German team, pick which player we gonna swarm and who will ambush and flanking any help that may or may not come........
Now, let me hear how is that good for micro and tactics please?
Or you just said that, without ever taking a moment to try to picture what 4v4 might look like.
playing 1v1 and 4v4 is completely different, trust me I play both.
