Only reason this tank doesn't get a 5 is due to its lack of mobility, as most people would have guessed. In some cases, such as holding / pushing a corridor or holding a ridge, this tank can be flat out better or at least as good as many 5 star tanks. E3 is a very reliable assault TD which can easily serve the role of a heavy tank as its combination of armour and ammunition choices will hold up and exceed what is required of a ''front line vehicle''. The characteristics of this tank are good enough to warrant the grind and in my opinion outweigh the mobility cons. Question remains whether or not this playstyle is suited for ''you''
