It would have been a fine stock unit if the spirit of t4was kept. T4was supposed to be a siege breaking tier. Powerful units that you can tech up to and roll out when the game grinds to a draw. The problem is they wanted these siege breaker units to be more accessible and stupidly, an alternative to the standard units so Concessions had to be made. Disregard for design considerations make balance redesigns a messy ordeal.
With last commander-revamp we missed some possibilities, but I think we get some chances in futur for some revamp too. StuG E and Brummbär got so many changes in last years, maybe it would be time to make some intern tests to see what it will bring to change them with each other. Maybe move Ostwind in T4 instead and StuG E into T3 etc.
There are some things I would like to test with community, Ostheer is my love-fraction ^^
a. bringing back 221 for Ostheer, make 222 more expensive but more powerful to fill the gap of light/medium or make it a seperate more expensive unit.
b. make StuG E a non-doc T3 unit, to fill the gap of long-range AI on non-urban maps.
c. make Brummbär a commander-vehicle, a real unique unit.
d. make Ostwind a T4 unit, with larger focus on AA.
+ some smaller changes
But I also have many ideas for other fractions too.
Main-thing is to have a huge repertoire.
