That's mainly 'cause he keeps trying to play Sheik instead of Doc though. lol Shroomed was placing top 8 at nationals fairly consistently back when he mained Doc.
Well, if character switching has taught us anything, the changes have been predominantly lateral (Mango's peak skill isn't too deviated from character to character, Hax took a while to surpass his Falcon; still lost to Abate after the switch, etc, etc.)
Shroomed got 13th at Apex 2014 going primarily Doc. His performance at SKTAR 3, MLG, Evo, and Big House have been roughly the same going mostly Sheik (though the Doc is brought out time to time). I don't think it has much to do with his character choice, just that he isn't as relatively good as he used to be.
Pikachu is a bad character, but falcon is also pretty terrible. I dont think it really matters if falcon is higher than pika, however it is true that if pikachu blows vs both spacies then falcon is straight up booty butt cheeks and MUs vs spacies define character relevance and will only continue to do so more. In that sense a reasonable argument does exist for pika being higher (not that Id personally agree). I do agree that falcon has a much better MU spread vs everyone else (maybe not jiggs? pika seems to lose but its not too bad).
Could you explain why Pika is considered so bad vs. Spacies? I've often seen the mid and low level community (particularly pika mains) say he is bad, but commentators and high level community play him up. Why the divide?
I mean, I can understand disadvantage in terms of some of his priority and his low tier shield, but its not like he doesn't have the mobility to work around those issues. He probably eclipses Marth in terms of edge guarding, has a uthrow chaingrab that basically auto kills on FD and nets like 30-50% on Dreamland, uair has insane backwards and platform coverage, he can be very difficult to gimp and edge guard a lot of the time, etc.
