Τhere is one thing that most of you forget about
Game Freak's competitive POV is the VGC
Most of you use Smogon as competitive POV so Mega Luke sounds too op
But let me remember you that 2014 VGC Champion won with a Pachirisu
There is not tiers on VGC
Last thing is that some Megas are for fun, some for in-game some for competitive, what competitive? Make ur choise
