If you see people being brawler with T34, you can say this guy will dead so fast. This tank has nothing but gun. Think about GUN.
Keep range is most important. You have only 220 m view range, most of the tank will spot you and hit you first before you spot them.
If you can't reach any obstacle to hide or hull down within 3 second, then you're in open field. Keep moving around the buildings, obstacles or anything that make you feels safe. One more thing, do not be attractive. Let your team go first then check the good spot to help them because if enemies are busying fighting with your teammate. they will not change target to kill you easily unless you approach them from the front.
This major problem of this tank is so weak. CAN'T carry the GAME AT ALL. If you team doomed, you doom. Simple rules. I played this tank over 1000 battles I could say I love it so much but hardly to survive due to lacking armor and very attractive to all enemies to shoot you first. But over 95% I am on the top of damage list.
You need to find a good spot in each map to allow you sit and help your team hitting the toughest tank first. Patiently wait for aiming, you can afford of bounced or missed shots. Because this tank has very good gun depression about -10 degree so you can use bridge to hide your hull and pin your gun out and shoot. Only some of T9 and T10 tanks can pen the turret front. Wiggling will prevent that except dang E100, spamming HE on your turret.
This tank is hardly to survive in T10 battle if your team go potato.
Also you need a lot more skills to play this tank and a good situation awareness to win in this tank. Not a friendly tank like IS-6
