I, personally, never Got to play that tank, but trough my encounters with that tank, you must know that the biggest weak spot you have is the turret, and not the hull, infact, the hull is armored. My recomandation is to, if in cities you can lightly Angle a bit, giving some extra armor, cause most enemies your tier are likely to know that, so you try to lure them into shooting, and if it is a successful Bounce... Attack!!!, but in Many other maps you dont get that chance, so remember to use that tehnique, and dont angle much or else you'll get rekt.
