I wouldn't merge the Shock-nade into the commander slot aswell, certainly wouldn't make it non-doc that would be way to much. No stock infantry has 3 nades in his utility-loadout.
I have the idea, because I would like to see:
- HMG42 moves to T1, or gets replace by HMG34. (my first move to make game less HMG cancer) but to compensate blobbing without HMG the non-doc Schock-nade would give Grens more tactical advantage, so e.g. they can use the timing to fall back or use the ability to circle Maxim-blobbs while staying balanced, Schock nade is a micro-tool.
( I am working since some days on a small Ostheer revamp changing the teching a little bit and move around some abilities and units e.g. making StuG E non-doc instead of Brummbär)
