>>28383746I mean... yes, it did.
>>28383811It damn well is. Compare it to Gengar. Both received a Mega Evolution in Gen VI. Alakazam's BST before Gen VI was 490, then it got extra SpD to boost its BST to 500. Gengar's had a BST of 500 ever since the Special split. So at their base forms, they have the same base stat total. They're supposed to be counterparts of some sort. Both have advantages against each other (Alakazam's Psychic vs. Gengar's Poison, or Gengar's Ghost vs. Alakazam's Psychic) and both are heavily Special oriented.
And yet... when Mega Evolving, Alakazam only gains +90 to its BST while Gengar gets the standard +100 like every other Mega. It's just nonsense. Ampharos, interestingly enough, also had a 500 BST, but got extra Def making it 510 BST, and then still got the usual standard +100 BST when Mega evolving, making its Mega Evolution a 610 BST Pokemon.
