Imba Heavy Tank?

[Tribulation]

Towers are static, you have to defend them against mortars, of course a static target alone has no chance against a long-range artillery, that's the point of having mortars as a counter to towers. Again: heavy tank costs far more than tinker, it's gotta be far more powerful. Plus, we already have a good suggestion for modifying the armor.

P.S. If a single player, or two, could end a game in 20mins with a heavy, the others fucked up.
