the raketenwerfer is over performing in many ways
1 , is that its available without any tech or upgrades and comes for a really low price for AT guns.
2, it comes ready with a ability and the ability is camouflage,the ability can be used for reasons or ways a AT gun shouldn't be doing , it became a really strong recon unit , even better than a sniper, doesn't need cover to camouflage moves at a really fast rate , and also can capture points while stealth
3,it ability to retreat at a very fast speed , so it can hit and run even faster than infantry movement speed, so when ever its in danger it easily just retreat out of combat
4, it shoots at a really fast speed, faster than ZIS-3 and Pak40, so you can move it in stealth mode to the enemy vehicle and hit it ,and have the chance to hit again without the the opponent having the time to react and fallback .also it can reposition or change angle at a very high speed,it also have a very fast tracking speed faster than other AT guns, which makes it really hard to flank it
the only drawback the raketenwerfer has that its just a have slightly less range that other AT guns,but thats not a real problem,as it have a extremely high penetration chance,and a really fast firing speed which can easily give mutiple succesful shots in time the vehicle is in the raketenwerfer range.
ways to be fixed:
fixing ability:raketenwerfer will only be stealth while in cover and stationary, and will go auto stealth as a passive ability, or a active ability which whenever raketenwerfer is stealth it wont be able to move at all
fixing fallback, as its the only AT Gun can fallback, it should have a drawback,of decreasing the reposition speed and making it slower in moving up the gun, and also slower in movement of retreat
