It not a light vehicle it is a light tank. If it arrives later it arrives later than OKW vehicles so delay those vehicles.
Lower the price of the T2 truck so it set up in the same time as T1 and have vehicle production (puma? Stuka?)require engineers. Now Puma comes later.
This is OKW issue.
Arguing about the semantics does not lead us anywhere.
Both OKWs LVs and the T70 arrive according to their cost and performance. There might be slight rebalances with some units but all in all it is okay.
I'm actually not sure what the current argument is about. The T70 is a very strong unit, but it also has the shortest time of all LVs where it can roam freely. OKW T2 has the perfect counter to it. Also the T1 FHT can significantly damage a T70.
OST is a bit on the short end since zhe T70 both amplifies the weakness of OST (4 man squads vs high wipe potential of the T70) and the lack of a LV counter. I find that a supported 222 can do the job decently. The autocanon can do decent damage especially vs the side armor. And no SOV player would dive his expensive T70 to kill a 222. It takes a lot more micro to pull off though. The other options OST has is a StuG rush or depensing on the map Panzerschrecks. Tellers can protect vs dives but it also requires a lot of skill and micro to bait units onto mines.
So, final conlusion of mine:
T70 is strong, but no major readjustments needed. OKW can counter the unit perfectly, OST might need a slight rework, but I think this is not specific due to the T70 but more the faction's power spikes in general.
