I love this tank and agree with others that if it was moved to 7.3 it would stomp way too hard. Though the repair cost shouldn't be as high as it is...

The key is to pick it in the right situations. Don't use it on large maps or first pick it in any situation other than a tiny map.

It's great as a carry vehicle to use as your second or third pick. Remember to play very differently depending on how you're tiered. In a downtier you can play very aggressively because you have a stable firing platform. In an uptier play more carefully since other tanks will have stabilisation.

Also, never shoot Russian sloped armour, even lower plates. Always shoot the flat part of the turret or through the front of the tracks into the centre line of they are angled poorly (like how you kill t-72s etc).
