Arguing about the semantics does not lead us anywhere.
It not semantics it is of essence. Some light vehicles can be killed be small arm fire, most light tanks can not, these vehicle are of different category. One is forced to invest into anti vehicle counters vs light Tanks.
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.
And this is the point. T-70 should cost less and be less lethal. If that means that OKW T2 should also be timed later so bit it.
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.
Again is more about Ostheer than OKW
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.
So lets tone down these power spikes and improve the game.
