I haven't played the lower tiers yet. But here is my thoughts on the tier 10.
It's armor is absolutely insane. If you want to pen it frontally you have to fire gold and even then if you don't hit the lower plate it's very hard to pen frontally.
The speed is meh, but that's good for balancing.
The gun. Oh god the gun. The gun feels absolutely horrific. I played about 20 games in it today and the same thing every game, very good armor, but the gun sucks so much. Firstly that intra clip reload is just so bad. 8 seconds lol. It takes 32 seconds to fire the whole clip and only 21ish seconds to reload the clip… It's burst potential is god awful. It's accuracy is pretty horrific even with aiming device. The pen is pretty meh. The bloom when moving (or turning the turret, I don't quite remember) is HUGE. Aiming speed is meh. Alpha is alright I guess. This tank is a must be front line tank if you wanna do any sorts of damage. But then that 8 sec intra clip just holds the tank back so much. I'll play more games in it tommorow and see if something changes.
All in all I would say I feel like the tank is kinda balanced but kinda not cus of the insane armor. I have all the tier 10s already, and even then I don't feel like this is a tank I will want to get when it comes to the live servers. Tho I probably still will. I definitely don't think it will be a good tank for newer players or players with only a few tier 10s to get. But I guess that depends on your play style. People who played it today as well, what do you think?
