I heard that T62A is too slow compared to other mediums and Patton is OP. I haven't tested neither of those so can't really tell. And yea, test is only test, anything can still change..
I did few battles with new BatChat and I liked it. It probably isn't as overpowered as before but it's still good. I believe it's kinda same situation for every tank in French medium tree.
I most likely won't even buy T-44 but just research it and then continue grinding USA heavy tree and french artys. I've heard that T-62A(new soviet tier 10 medium) isn't as good as new Patton III/BatChat.
I bought 3 of those for price of two from Gamestop few months ago. 7500gold+3weeks premium+Pz38H was much better than 5500gold from official sites. I do understand why WG doesn't want to sell those boxes anymore.
Currently I'm playing mainly T-43, because I must get T-44 researched before next patch when T-43 loses its best gun. T-43 is actually pretty fun tank to play, although it is practically almost same tank as T-34-85 with more hp and tougher matchmaking.
Also, I finally got Ace tanker badge for my BatChat. Replay is here in case someone is interested. Wasn't anything very special really, just general autoloader raping+a bit of luck, 2101exp.
You have 800k unused exp and you still need more? I have around 300k and I'm accelerating crew training cos I just dont need more exp until I buy some gold. (Which may actually happen very soon. Researched Lorraine and now I need some experience cos dont want to play it as stock :schwitz
4.4k battles fought overall and currently I have 3 top tiers in my garage: E-100, E-50 and T-50-2. Currently I'm focusing on French medium tree, going in AMX90 atm.
And because whoring with stats is fun I have to mention that I've got 9 Ace Tanker badges.
