Personally I felt that Megas were just another way to cash in on nostalgia for older Pokemon and pretend that gen six wasn't terribly short of new designs, a bit like the new fully-evolved forms of old Pokemon in gen four. Hopefully Sakurai sees them for what they truly are, in my opinion, a cynical gimmick, and we only get a final smash or two. Imagine if Mewtwo ends up as one of his ugly 'Mega Evolution' forms, over his classic design.
Here's how I see them.
The issue wasn't how many evolutions there were. The issue was who got them.
This could've helped buff a ton of Pokemon who needed it since forever.
But instead they just break the already broken Pokemon even more broken.
Let's face it, other than cool points, did Mewtwo really need
two evolutions? I don't think so.
Or heck, Charizard. Why should he get two, when the others got one?
And let's not stop there. Why did Gen 1 get the majority of them, and the other got the table scraps.
If I'm correct, Gen 5 and Gen 6 didn't get any at all. Yet somehow Latios and Latias get one.
Better yet. Why Blaziken, when Swampert or Sceptile need it even more?
Though, to be fair, there were some that got a justified buff.
Like Banette and Medicham, they've needed it since forever.
This could've done something big. They could do great things with this idea.
If used right, it can bring hundreds of Pokemon right back into the metagame.
But instead, they only use it on the popular Pokemon.
It just feels like a way to make the them even more "cooler". With a couple others thrown in.
