God tier (200MP): Stug-E, Stuart, T-70
Mid tier (200mp, but weaker): 251, 222
Low tier: m20 (340mp) Luchs(340) Puma(280) aec(380) m5(280)
I wouldn't be so hasty with placing T70 as a god tier. Why? Becasue you look only at the units' costs but if we take a bigger picture it's not god tier anymore.
First Luchs needs 615MP 115F.
First T70 needs 600MP 175F (with T2 start).
It's 60 more fuel.
But what's more important, once Luchs hits the field, OKW already has incendiary nades, pzfausts and access to schrecks.
On the other hand SU player has to pay for this. So T70 is way more expensive in terms of fuel but if we add at least AT nades or Molo upgrade, it becomes the most expensive light vehicles in overall view.
