Even 60 wouldn't make it a monster. Worse canon than all other tank-hunters, way more expensive. Even it's AI power is so bad, that on 60 range it would lose versus a PaK. Maybe at Vet3 with its hard reload buff it would become OP.
But 50 range would make a decent all-rounder at arrival, and then the +5 buff at Vet 2 would make 55 range. So it gets a small advantage.
60 range would absolutely make it a monster. It would be the same as an allied TD, but with machine guns, armour, nearly double the health, blitz and aoe on the gun.
Don't get me wrong, I'm arguing the tiger is a bit squishy due to the potency of its counters but let's think about balance here while we make claims yea?
50-55 range isn't going to help the tiger quite against the thing that is pressuring it but turn the balance on its head against everything else that it isn't underperforming against.
Its just like buffing TDs because of the KT and panthers and ignoring that they now invalidate all armour values below 300 (which is most)
