Don't you play Armada like...all the time though -_- I mean maybe you're right but doing well against him when you only see him at big nationals is significantly different than doing well when you play him all the time.
I would concede more to Shroomed's point of there being a lack of knowledge about Pika on Armadas part that made Axe look better.
I also don't understand this argument of "he's overrated because he uses a mid tier". Like, how can you overrate someone using a worse character? If he's performing as well as people using high tiers is it not logical he's BETTER than them? He's achieving the same amount of success with poorer tools.
I understand the "we don't know matchups!!1" argument, but it gets to the point where he cant keep winning with a mid tier off of surprise value.
Think about it, hypothetical scenario where a Kirby main goes and sorms on to the scene. He whoops many C tier players into the ground and goes on to defeat a ton of B tier and even A and S tier players somewhat convincingly. Could we not assume that this guy is an inherently amazing smash player? A player that, maybe given the time and motivation to use better chars, would definitely pervade the top eschalon of players?
The fact that Axe essentially DEFINES Pikas metagame is something in its own.
TL;DR you can't overrate someone using a mid tier char nearly as much as you can underrate them
