Lol so "l2P" is mostly what you mean here?
I have a pretty hard time believing a large number of ppl are skipping to tank depot. There's nothing there worth rushing out...
Getting a greyhound as early as possible is one of US strongest plays. What loses ppl games is motor pool timing. If you prioritize anything else or fall behind in fuel, thats where whirbelwind and FV timings can kill
You can call it that.
Nothing aside from Bulldozer, EZ8s, Whizzbang and Hellcats? Axis blob destroyers, best medium, blob crusher and potent fast TD in that order. We've had 0 extra CP unlocks for the certain vehicles from the Tank Depot for quite a while now.
Of course Rangers are also your armour, so you don't 'need' the Motor Pool for Adv Inf unless the Stummel spam is obscene and you fail RNG on the zooks badly. But Rangers are also a crutch where you don't learn skills properly and hurts you long term IMHO.
