Leopard 2PL

Why Leopard 2 PL is at 11.3 and its Vlll tier meanwhile T80UK is 11.3 and Vll / new udpate Leopard 2a4m CAN too 11.3 and Vll / M1A1 Click bait too 11.3 and Vll / M1A1 AIM too and couple others… Its hits me hard, because i need one germany (4/5) Vll to research tier Vlll. I dont mind about change BR Leopard 2PL i just wanna now why its not tier Vll like other vechicles at the same battle rating up here??

APFSDS stock or not basically.
If the tank has any sort of armor against ATGM and gets stock APFSDS then its moved to rank 8.

2PL fires a similar round out of a worse gun while being significantly faster with gen 3 thermals and adequate armor.
