2nd anniversary: do you remember Beta?

LiannaSilverwind: Analyzing last months of gameplay and popular forum topics, it seems to me that main difference between Beta and Present Time is that each tank had its own niche, kind of unique quality.
If we check modern companies and especially ESL gameplay, we'll notice that only certain tanks are useful, rest are just considered unworthy. Old slow armoured vehicles are obsolete and with more and more tanks present some tanks are just like "bit slower than X, bit faster than Y, bit better accuracy than Z, bit lower damage than..., but nothing particularly interesting".
