your 85 or any level in classic may not even be close to what you remembered or experienced in MOP
blizz tends to roll last patch and that is why they know this will gank MOP. they are rolling some classes at early, mid, and last patch along with selective reverts. they know that rolling last patch would make classes play like WOD in MOP. which was a major squish and pwer nerf not like other classic versions, where rolling last or next expac per-patch balancing made them overpowered for that classic version.
i am not going to mega list, here are a few
- OP healing/hybrids was never truly fixed until end.
- subterfuge rogue admitted by blizz as OP 3/4 thru expac, did nothing, let it ride until end
- FDK was slammed on end
- feral became near god mode on MOP last patch
