>>26500360They were a bad addition to the series.
I like the idea, and I like most of their designs, but from a gameplay perspective they're a trainwreck that just makes everything worse.
They turn your pokemon into a one trick pony, and about 75% of the time that trick is fucking worthless. The remaining 25% of the time, that trick is so obscenely overpowered that it sucks all the fun out of the game.
For most pokemon, their mega either does nothing at all to fix their problems, or is a straight up downgrade, base stats be damned. It's just adding insult to injury because that pokemon was already shitty to begin with.
The worst part is that most of the good ones are on pokemon that were already good, and the only reason they use a mega is because no other items give you +100 BST.
I guess you could say they're wasted potential. They were a great idea that GF was too chickenshit to implement properly. If we never got another mega evolution again, I'd perfectly OK with that. It means more effort and development time spent on things that actually matter.
