@ Drake 512: Flygon's a popular Pokemon among the fanbase, but it doesn't get a whole lot of attention due to it being overshadowed by Garchomp in most areas, so its fans want it to have a Mega Evolution so it can be more competitively viable (hey, it worked for Mawile, so why not Flygon?). And maybe it's just me, but the majority of the hate for Mega Evolutions I've seen comes from their designs, which are considered to be overdesigned compared to the originals, and not their competitive value, which is give-or-take (some are broken, some are outclassed by their base forms, and some don't fit either category but can still be viable or near-useless depending on the situation).
