Volks>>vanila grens now.
I wouldn't call that marginally.
They are marginally more expensive though if that is what you meant.
Luchs arrives 1-2 minutes BEFORE T-70/stuart and if you believe JP4 is useless, you need big, fat L2P.
1. Grens being bad isn't pertinent.
2. Please, rush Luchs and see what happens against players who know how to mine.
3. Why get a JP4 when you can get a Panther from the same tier?
