Seal Clubbing Tanks?

Lert: Being very good, borderline OP tanks at a low tier - or having easily exploitable mechanics that make it OP in good hands.   T-127 is a very good all-round package with ok mobility, good armor for a light and an ok gun. Su-76i is another good all-round package, similar to T-127 with the additional bonus of better armor and being so rare most people don't know how to fight it. Marder 38(t) and FCM36 Pak 40 can abuse viewrange and excellent guns for days, making them difficult to combat if you're new. Pz B2 is another good all-round package, but forsaking some straight-line speed and some firepower for even better armor. Plus, it's always top tier unless failplatooned. KV-1, dat armor when top tier.   And others that I'm forgetting.   Basically, a seal clubbing tank is any tank that new players have trouble combating.
