Only one selling point of this tank is pref matchmaking and hope that you will be top tier (play against tier 6 and 7).
It is just outdated.
Armour doesn't hold against tier 8 and gun handling is pretty bad.
Don't get me started on pathetic premium ammo penetration.
In theory you should go to the heavy line to make pressure or to hold the line, but it works only against tourists.
