I dunno, it's nice that a Mega Evolution can potentially do something different than its base form. Charizard though could care less about Draco Meteor. Only X becomes Dragon-type, and it gets access to the much preferable Outrage thanks to Tough Claws. And a few Attack-boosting moves to make it even scarier. Not too sure about Mega Ampharos, though. Lopunny appears to be getting High Jump Kick, and that's really all it needs for Fighting moves. I think Game Freak was done with evolutions to previous Pokemon by gen 5. They could have still made some that were only available after obtaining the National Dex, keeping with Black and White's gimmick of no old Pokemon until the National Dex, but they didn't and again chose not to this generation. I'm positive Eevee will still receive one or two every other generation, at least until there's an Eeveelution for every type save Normal, but that's it. And I'm utterly baffled as to why the hell anyone would want pre-evolutions. They'd require some stupid Incense to breed, and are almost always a pain in the butt to raise, all for the sake of being heart-meltingly cute and one or two (egg) moves the line wouldn't otherwise learn. I'd be perfectly happy if we never see another pre-evolution for previous Pokemon.
1. I'm okay with a Pokemon being able to do something different, but it just seems odd for that to be it's sole Mega Evolution. It would be like if Mega Mewtwo X was the only Mega Mewtwo. It's VERY powerful and kicks some serious behind, but it's far from how Mewtwo originally plays (that said that's another Pokemon who needs moves to make use of its type change. Mewtwo's strongest physical Fighting-type attack is BRICK BREAK and it doesn't get Psycho Cut or Zen Headbutt!). We need a Mega Move Tutor, some guy who you can show a Pokemon with a Mega Evolution too and will say "Oh, that Pokemon has a Mega Evolution that's so and so, I can teach it these moves so that it can REALLY break loose with its new found power". Obviously he'll be a post-game character and probably be in the Battle Frontier or similar place (and require shards or another hard to get item), but I think it would be worth it.
2. True, but it would be nice for Charizard to at least have the option, I'm sure Mega Charizard Y wouldn't mind being able to summon meteors to hit Dragon-types even harder with it high Special Attack (sure it has Dragon Pulse, but 130 compared to 85 is a bit of a difference).
*M-Charizard Y fighting with M-Charizard X*
Mega Charizard Y *mocking M-Charizard X*: ~Ooh, look at me! I'm part Dragon-type now and everyone LOVES me, even GameFreak! They love me so much that they apparently forgot they gave my another Mega Evolution.~
Mega Charizard X: Oh, boohoo, jealous?
Mega Charizard Y: Maybe a little, but you know what I'm not jealous of?
Mega Charizard X: What?
Mega Charizard Y: Dragon-type weakness. DRACO METEOR!
*M-Charizard Y uses Draco Meteor*
Mega Charizard X: Son of a-... *Draco Meteor hits* IN MY DYING BREATH I REMIND MEGA CHARIZARD Y HE'S STILL 4X WEAK TO STEALTH ROOOOOCK...!
*It's super effective!*
3. Mega Lopunny looks like it could be a Close Combater. Maybe also Drain Punch but that could be pushing things. Of course both moves will be Egg Moves so you'll have to choose between the two.
4. For BW I was willing to let them get away with it as they were trying something new. Make a generation which didn't rely on any old Pokemon. That meant they pretty much needed mainly all new Pokemon and they did a nice job, of course they threw that idea out the window come BW2. But with XY they introduced the Mega Evolution idea and decided to double down on it even though they had no clear idea where they fully wanted to do with the concept.
5. I wouldn't write off a Normal-type Eeveelution. Normal-types deserve just as powerful Eeveelution as the other types. Obviously it'll be a result of something gimmicky but if done right I can see it working. Or maybe have the Eeveelution Mega Evolutions be half Normal-type, that could work too.
6. I think they need to expand on the Baby Pokemon idea like maybe have them learn some Egg Moves naturally or even moves that Pokemon can't normally learn. Pichu can learn Parabolic Charge, Cleffa with Draining Kiss, Igglybuff with Boomburst, Togepi with Defog (have you seen Misty's Togepi cry? That thing has lung capacity), Tyrogue with Sucker Punch, Smoochum with Aura Sphere, Elekid with Wood Hammer, Magby with Eruption, Azurill with Rapid Spin, Wynaut with Moonlight, Budew with Sludge Wave, Chingling with Perish Song, Bonsly with Head Smash, Mime Jr. with Moonblast, Happiny with Nightshade, Munchlax with Slack Off, Riolu with Mach Punch/Drain Punch/Water Pulse, & Mantyke with Roost. And these are just examples. Of course this is a Mega Evolution thread, if we want to delve deeper into this topic it could probably make for a thread of its own.
