I just want to point out while its fire rate may be good, its aim time is still painfully long.
Also while cammo is nice, its only there to balance out the negatives of its short range and lack of survivability. Camo may be good, but firing from 60 range and from the FOW is better.
Whilst i understand that the aim time is rather long, do keep in mind that obviously the cloak is supposed to counteract this(and garrisons though thats dependant on the map more than the raketen). The raketen fills its own role as an ambush tool rather than a direct AT gun, which has its downsides and upsides.
The problem is when such a weapon is put in place as the only AT weapon at T0, aside from 1 pointless shreck on your engineers(should be 2 for 120 when 1 truck is set up imo, but thats another topic). Mines/panzerfausts won't reliably kill early light armor unless used in mass, and even then it is a hefty muni sink which is not always available. This is why the raketen needs to be as reliable as other AT guns in other departements like aim time and range, without making it a Pak40 clone.
At the same time, i don't want the raketen to be the Überblitzpowered AT rocket launcher that can wreck every light/medium on its own, let alone 2 taking care of pershings and IS2's with merely a couple of volleys.
So to simply sum it up, i find it difficult to find a solution.
