That's combos. Everyone in this game has combos for crazy damage if you let them have it. I'm talking neutral game, spacing, mobility, etc. Olimar's relies on hitboxes and sideB, and sideB can neuter you in this game if you use it recklessly, while in Brawl you could do whatever you wanted because you had so many Pikmin and neutralB was fast as all hell. That's why he was good in Brawl, alongside having his whistle armor and a floatier, slower game that allowed him to recover more than usual and space even better (though his recovery was so *** it didn't really matter). Now whistle armor is gone. He has -no- mobility in a game where mobility is much more key than any other Smash, no other special tools on stage except projectiles that throw your Pikmin away from you. He is -all- hitboxes and sideB. G&W has much more than just hitboxes and has a decent projectile now that can be crazier than Pikmin, alongside his crazy-*** upB and dair. I would rather play him.
Charizard's upB is okay, it can kill, but for recovering? The thing makes me want to cut myself. It's hilariously slow and the recovery at the end of it is laughable even when you try to sweetspot. (He also still has problems with his long *** neck/head) If you DON'T sweetspot, he hovers off (without being able to be controlled at all) for so long that even a monkey could punish him. DownB is his only other real recovery option, and that takes away all his jumps, while having very bad options to recover out of it with (downB attack is nice, but it's awful to recover with unless you platform cancel it. You can even crouch cancel it to certain percents). Pit doesn't have to commit to crap and all of Metaknight's specials are recovery options to mix things up, and he gets more jumps. Why does Charizard hurt himself by trying? Yes, they're very different characters, yet Charizard is a much easier gimp. He has that Southwest Airlines recovery.
Everyone has combos. -Everyone-. Combos do not make you a better character.
