We can't make assgrens super good because that will affext a powerhouse doctrine and only that doctrine. It's also the fact that they rush out at 0cp.
Regardless, judgong from your comment I fail to see how the changes don't improve assgrens scaling.
Lower mp cost and sprint allow you to close in ehile bleeding less.
Thr goal of assgrens is not to take lategame closerange allied infantry head on. It is to flank tean weapons and dispose of them.
Finally assgrens already cost only 5 popcap, which is the lowwst in the game for any infantry squad.
Mr. Smith, what about removing the PTRS's From penals and adding the 45mm M42 AT gun to Teir one and making it as expensive as the current zis 3 just it comes out earlier and is more a hard counter risk/reward.
Currently it's just sitting in a doctrine that nobody really uses and is more just a novelty. You can't put it in late game because it's useless then, experiment with an iteration of maybe teir one locked behind AT Gernades
