>>51175609On garchomp or an already strong pokemon, yeah its cheating.
On fucking Beedrill or some other shitmon, it makes them actually usable.
Mega-evolution is an S-tier mechanic that they dropped for only downgrades, and gave a terrible distribution. Megas was the best opportunity since the introduction of abilities in gen 3 to properly balance the game and give all pokemon at least a chance to be good, but they wasted it.
