Come on, when have Pokémon fans ever overthought something based on circumstantial evidence and gotten pissed when it turns out they got things wrong? I mean aside from all the times it happened, it basically never happens. Besides, if it did, the fandom would be smart enough to know by now that flavor text doesn't always mean the maximalist interpretations of said text.I mean, I am also mostly joking about how speculation can kind of take root based on so little.
That said since you leapt right to the GF are incompetent part of the discussion horseshoe: All they said was it had a buff to attack & defense! I don't think there's any dumb decisions to call out on unless it mysteriously doesn't buff defense beyond like 10 points. And even then at that point my raised eye brow goes towards the people responsible for writing the blurbs.
Realistically though, I can imagine that the attack/def buffs would be basically a +25-40 pt buff and maybe an ability like scrappy or whatever they thing fits while also being decently strong. Not all the abilities Megas get are that flashy.
