Requirements for Thunder Tank and above - Standard?

[horselance]

That just came from the fact that before the requirements came Inf was really imbalanced, so everyone just tried to get as fast as possible to the infernal

Fact is that, it is still race for infernal. Still we try to buy an infernal ASAP.

Whatever. This will limit all tanks. And will make a time-stair for game. Do you want to make variety of gameplays or standardize gameplay?
If some tanks are too strong for their price, then make them more expensive or make them nerfed. (this is the xx.th time I repeat this)
