That is simply incorrect.
Do you think the Scott needs to be nerfed? Cause I said it was fine, so I really don't care if you disagree. It's not "simply incorrect", you disagree. Congratulations.
Scott have some of the best defensive properties that include:
400 HP
19 size
7 speed
40 Rotate
Defensive smoke
barrage on the move
Some of the best? First of all, why did you list 400 hp? Being a t4 vehicle with 400 health is not a positive, and it needs all the other things you mentioned specifically because its
health and armor are so low...
If a player find himself in situation where his opponent has medium tanks and he has not AT assets he probably has done something wrong and that has nothing to do with performance of the Scott itself.
If I need OTHER AT assets to protect a t4 vehicle, that unit is by definition hard to keep alive. Your mistake is assuming I'm saying that there's something wrong with that. Snipers can be hard to keep alive too, and require other units for protection.
