Im all for the original experience but changes have been made to other classes, time for pets in general to get some love.
I personally enjoyed playing Classic/TBC/Wotlk when it was retail as BM, Hunter in particular is about having a pet, but by not having the scaling forces hunters to move away from the pets which kinda dampens the class.
Blizzard nerfed BM hunters at the start of WOTLK to push players to SV/MM, with few exceptions that trend has remained to this day, even right now in retail BM is one of the worst dps specs in the game and is downright terrible.
So the chances of you getting what you want are literally zero, Blizzard seems quite consistent with keeping BM as an easy to play but low dps spec.
