Standard grenades might feel RNG because grenades drop-off and any slight movement will generally affect the AOE, especially when you get to the outer edges.
A USF Grenade goes from 1/0.75/0.25 in terms of damage with an AOE of 4 and a distance of 1/2/3.
Bundles could probably have their damage dropped from 120 to 100 as they still have good AOE distances. Gammon will always be an issue given its on a cloaked squad.
And since when did Axis have no real munition sinks? Soviets are the only one who no real munition sinks unless they go doctrines aside from mine or demo spam and....PTRS spam(?!).
Considering the ridiculously high price on the Bundle Grenade, any reduction in power should come with a price drop.
And many Ostheer players have started to realise how shitty a deal the lMG 42 is on many (not all) maps compared to the G 43, due to the massive reduction in mobility (or better worded, the massive amount of DPS lost when fighting at anything but max range, due to the model holding the MG constantly moving and realigning the gun instead of firing).
This in turn has led to a much higher availability of ammunition points, because the G 43 is cheap and plentiful.
