Don't go Russian TD line if you don't want to get pissed off and delete game. SU-100 is OK but SU-152 with 122 mm gun and ISU-152 are pain in ass, until you get the good T10 gun (eternity without premium). Of course object is another story. My advice for newcomers is: Go Russian medium line T-44 and T-54 are fantastic tanks. You gonna love them. T-62A (currently have him) is also fantastic tank, has huge punch of around 3000 dmg/min, fantastic gun but has weak armor and takes experienced player to play him good.
Go on Tiger 2, E-75 (to me best T9 tank, fantastic armor and gun), and of course his royal highness THE E-100 with 150mm gun and gold ammo. NOW, THE BEST TANK IN THE GAME from worst tank in the game. 3 of us from clan in E-100 and gold ammo, now that is fun and broken desk, keyboard and who knows what else with enemy. We win almost every game. On Russian heavy line, IS-3 is great tank, but T9 and T10 (IS-7, IS-4, had them, sold them) are not so good any more. Why?? Because of gold ammo for creds. Main thing about Russian heavy line is armor, and armor is irrelevant when you load gold ammo, and their guns have slow aim and low accuracy. They are still good tanks but not as before.
French are nerft to hell. Very hard to play, always at back and snipe, and easy to kill. Bats is still fantastic if you play him right. But if you don't think while you drive it will bi like LoLTractor... Very quick and painful death.
American tanks are very special. Try hellcat and dont play him like TD noob in bush, but use his speed and get on sides and backs of enemy. Use strong turret on t8-t10, use terain to hide everything but turret, use gun that can go very, very low.
