Here is my experience in 95% of the games I have played:
- Enemy mortar is wiping my squads on the move with no vision. My mortar cant kill an MG that has never moved all game long.
- My LeFH kills next to nothing all game long. If it does enough damage to get to vet 1, I will finally get kills on counter barrage. Enemy LeFH chases my units around the map killing them on the move.
- I throw a grenade on a squad, no damage. Maybe get one model dropped. If I see a squad moving towards me in a manner that looks like they MAY throw a grenade, I retreat... and lose 4-5 models every time. It makes no difference if I move, am in green cover, etc. 4-5 models every time.
- My AT guns and tank destroyers miss/bounce the first shot 98% of the time. Enemy pens every shot, every time. Usually from outside the fog of war.
- If I have a squad below 90% health and I retreat it, it is dead. It will not make it. Enemy can be at 30% health and just soft retreat away from me and take no damage.
- My team weapons get flanked they are dead in under 2 seconds. I flank an mg or mortar and my elite inf dies to the support team??? Seriously WHAT IN THE ACTUAL FUCK RELIC moments. Uninstall follows.
- If I click on an enemy squad to focus fire on that squad, my units stop shooting and wonder towards the enemy like they are blind and cant see the enemy. Even if they are 3 meters away. They just stand there like...derp. This happens about 30% of the time.
- MGs, Tanks, AT guns: Enemy is standing right in front of my units clearly in range but my units wont shoot at them. If I click the enemy then my units start shooting. This is REALLY bad with Raketens I have had vehicles park right in front of them and never take a shot. Entire blobs walk right thru my MG arc and it never shoots.
I could go on all day long. Just ask Sturmpanther

I have driven him to drink and ruined his life with my vitriol.
The only logical conclusion I have for most of these issues is server lag.
For example, the server decides your units are dead way before it actually happens. This was very apparent in vCOH, better in COH2. So on my screen I am moving units to safety all the time, but the ordinates FOLLOW my units around and kill them outside of arcs/cones etc. Ask Luciano how this feels and reference Angoville. Where arty followed his units around the base killing all of them.
If I hear "GRENADE!!!!" on my speakers, it was thrown and has already landed on me on the server. But I have successfully dodged it on my screen Boom. Squad gone.
So for me, moving units around and blowing stuff up is the ONLY fun part of Coh2. The rest of it sucks goat ass and makes this the worst game in the world. I gave up on ever winning games two years ago. For me, playing 1v1 would be evidence that I needed to be sent to a mental facility.
