After many days of playing, I unfortunately have to correct my initially balanced assessment of the changes to the game caused by the battle rating system and its implementation.
Unfortunately, the exciting games felt at the beginning faded away after a short time as soon as the more experienced players closed the gaps in the research trees.
I currently see the current battle rating and matchmaking as a step backwards, as the current matchmaking only leaves 2 playable tiers. And in my opinion that would currently only be Tier 2 and Tier 5.
With tier 3 squads you can only use them to fill up the games with tiers 4 and 5.
In my opinion, the vehicles are not the problem of an imbalance; the principle of rock, paper, scissors still applies here. Through which these can be combated effectively. I think that the diversity has increased significantly, which is definitely positive.
My concern here is the often extremely unbalanced distribution of ground weapons.
My Tier 3 deck only allows ground weapons like an MP-40, MG-34 or G41. But by constantly mixing it up with Tier 5 with players who can come up with max settings, these games feel like the Battle of Endor (slingshot vs. laser rifle).
Should I really fight with an early war weapon against comparatively overpowering precision weapons from the later years of the war, or those that can carry even more ammunition than my machine gun can carry? Such as M2 Carbine, M1928A1 Thompson, or even M1928A1 Thompson 100 in the Ardennes or Normandy, or alternatively against weapons such as AVT-40, Fedrov Avtomat or AS-44 in Stalingrad or Berlin.
Do you seriously classify weapons that fire 600-750 rounds per minute in fully automatic fire mode as self-loaders, which can then be used by almost every soldier in Tier 5? Here we should think seriously about limiting such weapons and not encourage their use to create further imbalances.
Another complicating factor is that many players received a few starting vehicles and weapons before the big update that increase their battle rating, while 99% of their remaining equipment is at Tier 1 level. Players without a rank or with a rank of Private have not lost anything in Tier 3, 4 and 5 matches!
Is this really the development teamās idea of a fair match distribution, or a better Enlisted? Are you actually playing your own game?
It is precisely these match constellations that often lead to the overpowering faction being able to run unchallenged across the map like in a jump and run game, hopping and firing continuously, and the players with inferior weapons being shot away shortly after spawning on the map and 0.0% can make game progress.
Unfortunately, I find these unbalanced battles extremely boring and would like to leave them immediately because they are a complete waste of time. 
Many players then do this, which then leads to an even greater imbalance and further ruins the gaming experience of the remaining players.
This means that in the end the only option left is to go into a game exclusively with Tier 2 or Tier 5 squads so as not to end up as cannon fodder here on the ground.
So somehow 3/5 of the game was made unplayable, and the update successfully removed it.
In my opinion, the previous campaign system was much more balanced.
I am also aware that the game is still a beta and that it may have one or two weaknesses or errors. And this situation is unlikely to change in the next few years/decade. I accept recurring errors that have since been fixed.
However, in the past and today the manufacturer already takes money for one or two little things in the game, and in one place or another not too cheaply. Before the update, I invested a few euros in the game because I enjoyed it. And the investment made sense at that point.
But now after the update I see my investment as a paying customer destroyed by the update because the items purchased at that time can no longer be played sensibly in the current constellation. Or itās no longer fun. In short, as a paying customer I have different expectations
I apologize for my sometimes drastic choice of words, but unfortunately that had to come out of me.
