I see where you're coming from with that. The Kubel can't be used to hold of flanks in the early game anymore.
I think that it is pretty indiscussable tho that the changes to the Kubel are a straight up buff to that unit. I don't really see any reason not to go for one in every game after the patch regardless of the map. It buffs the OKW's early game buy a lot as it adds an insane amount of mobility and harassment potentional. It's the only vehicle that is allowed to cap by default and doesn't even have a fuel cost anymore. Also nothing is said about the armor buff making it less punishing to get caught out of position and allowing to engage squads in the open.
I would trade suppression for those changes every day. That change alone would have shaken up things quite a lot imo.
I still don't really know what to think about it, a kubel with suppression can completely shut down a side in the early game, but with the current capping power of the OKW and don't have to full focus on capping with other units (which means they can battle straight away). Also I think it should cost atleast 10 fuel for that capping power
