okay tier:
>mega heracross
why the short legs? why slower? design is cool though, just wanted it a bit faster (95 base speed would've been more than great)
>mega gardevoir
okay design (kinda feminine but okay), meh ability, (and male mega-gardevoir being possible somehow)
>mega banette
awesome design, shit stats and ability for the kind of pokemon it is, it needs more speed dang it. an actual evolution would've been better. also, not learning play rough, cmon game freak (and ghost/fairy would've been amazing).
meh tier:
>mega charizard x
would've prefered it without the flames in the mouth, also two charizard megas, cmon gfreak
>mega blastoise
would've prefered with more steel parts (and water/steel) (or something else). like this its just boring
>mega alakazam
just a different ability, anything could be better on him, design is pretty good though, but it is kinda unnecessary though
>mega gengar
not feeling it, that 3rd eye looks fetchy, also kinda unnecessary
>mega tyranitar
eh. i see what they were going for but not working for me. also kinda unnecessary
>mega medicham
what's with the whole indian/arabian look? just feels forced and stereotypical, not that interesting. just all around "meh".
>mega latios and latias
meh. didn't need'em. not too shabby, i guess
>primal groudon and kyogre
who cares really, they're ubers anyway
>mega garchomp
"meh" again, too many sharpy things i guess
>mega lucario
looks ok i guess, but kinda unnecessary
shit tier:
>mega gyarados
unnecessary and stupid, the way i see it. mega golduck water/dark would've been better
>mega mewtwo x and y
the head on y and the neck and shoulders on x, man (and the toes on all of them, seriously, wtf)
>mega scizor
looks ugly af and also seems kinda unnecessary
>mega absol
why wings man. so many things they could've done with absol. edgy wings? magic bounce? kinda stupid
>mega diance
just shitty and stupid, introducing a legendary and then giving it a mega in the same gen. seriously game freak, come on
