>>50818437>>fucks over your favorite shitmon from getting a highly needed real evolutionHow so? Buffing abilities and signature moves already does that but better.
>>gives already strong pokemon even stronger formsHuh? Why were megas given to non-legendary strong Pokemon mostly sidegrades at best then? Why does it matter when they can nerf them individually as was the case with Mega Kangaskhan in Gen 7?
Gimmickfags act like that doesn't matter but it absolutely does. Z-Moves and Dynamax buff everything equally which doesn't bring balance. Megas can be tweaked over time by virtue of not being a gimmick which means any one complaint you have with a mega that's overcentralizing can easily be addressed without tossing out the good the mechanic brings.
