Interesting, as I do like hybrid tanks. One would initially say that this is simply a variant of another tank, but with the complexity of all these tanks combined into one, this could be accepted into the game. Although, as this tank comprises parts from the Type 59 as well as the M47 and M60 Patton, the level would be around in the high 20s. The thing with the developers is that they are not as much of fans of hybrid tanks as many of us are, and I understand that. Some of these hybrid tanks can be quite weird, sometimes TOO weird to add into the game. Although it is isn't too weird, this one is definitely one of them.
I'd like to go back to my other proposal to solve the problem with the implementation of weird tanks into the game of Tanktastic. That is to simply make these peculiar machines reward vehicles, whether it'd be for WWII tournaments or clan competitions. This solves the dilemma of having rather weird tanks in the game, but not seeing them that common that they mess up the flow of matches either. Anyway, a weird tank should be rare to obtain and find anyway, as they are not just "any other tank".
