Smash Ace
Sorry I'm late on this. Was at Smash Con (One game away from getting through phase one of pools ).On a more serious note, MArts are probably why he's screwed. Any change they make to him will be amplified by the arts, and a small buff to vanilla Shulk may mean an OP speed/buster/smash/shield/jump Shulk. The only change that would do this are frame data changes imo, but that's probably not happening because Shulk would become too dangerous. I don't see him going any higher than mid tier right now.
Any Shulk players out there: have you considered using MShield at lower %'s with the intention of making popular combo starters unsafe on hit? I know you lose what little mobility Shulk has and take a % dealt nerf, but with the reduced % and KB received + crouch cancelling, you might be able to retaliate immediately from a lot of moves. I see "shield's only good for stalling at high %" thrown around a lot. That's its main strength, but it can have uses elsewhere.
If Shulk got a few cooldown reductions that'd be just swell. I'd pay good money for spaced vanilla FTilt to be safe on shield. But of course like you say that could have ramifications on how good buster FTilt would be. Then again it's a frame 12 FTilt. Balancing this character is weird.
Also improving his bad moves is helpful. Backslash is actually kinda semi-workable now post-patch. I think giving him a better dash attack (Ike treatment PLEASE) and letting up and down air have weak lingering hitboxes would go a long way.
Shield does ruin low percent combos. I've done it myself in a few tournaments and it really throws people off who try to rely on those old BnBs. But of course higher level players will know not to deal with it and will simply camp you out. Therefore as of now I think it isn't such a bad idea for if you start your second stock in the lead, as they either have to approach and get punished on hit or they camp you out and lose 16 seconds to catch up. Plus even if they do hit you they're doing 2/3rds damage. Once you've taken a little damage though you might end up extending their combos instead, so you gotta look out for that. I cautiously say that Shield is super underrated by everyone not in the Shulk boards.
