An mp40s upgrade for incendiary nades is just as much a tactical decision.
Personally I believe balancing efforts should try to eliminate the need for such crutches as incendiary nades. I still maintain that the lava nade is a kludge of a solution and actually prevents OKW from exploring any other measure for garrisons.
I mean USF has never had stock access to flames and they have to sidetech for nades and smoke while having to go up against mg42s.
Mind you I've always suggested that Sturms and isgs have access to stock smoke as well. You can't explore changing up volks nades without improved smoke access. At least the isg has it now.
And USF has got the new mortar that was DEFINETLY a kludge of a solution...
What's the issue with lava nade, it is actually something unique and adds flavour and versatility that okw needs, it's surely not underpriced and now it's even "dodgeable".
If okw had something like pineapple + mortar it would be much more powerful as wipe nades and free anti garrisons would be more strong, and would be another mortar faction.
Smoke on sturm would be OP AF, at least if stock: starting smoke on a starting unit ? No defense against sturm rush.
Isg smoke was a good change, but that freaking thing has to gain some aoe, i need 5 barrages to even drop 2 models on a garrison.
