And I don't know if you know this, but you listed ALL +1s basically...and a -2 and an even. I don't even see how a lot of these can be disputed, by definition of a +/-1 they're all winnable if the player is skilled enough.
ICs, I feel like the "bthrow spike nana" is a lot easier to say than to do against a good icies player. +1 is fair We can hit them through their blizzard wall at certain angles, jab separates them like its nothing, and of course how easily we stomp Nana when she's separated. The fact we can safely bthrow is another huge thing. Its a MU with extreme momentum required, but at the end of the day it boils down to even.[/i]
Pikachu, fthrow CG and thundershocks are annoying, and he's as mobile as Ike so he can keep getting around and t-shocking. +1 seems fair This was explained better by someone else a while back, but it should be even.
Diddy - I could see this being even as Ike with a banana is really good b/c of his DACIT and quickdraw shenanigans. That is part of it, yes. Ike's range vs Diddy's range is another thing as well as KOing. Diddy's ability to wrack up damage largely negates the KOing differences though.
Pit - what does Ike do against Pit camping? +1 arrows Look up Ryo vs Kuro. I don't know how good of a Pit Kuro is considered, but he does go for the arrows obviously. Ike basically doesn't care that much about the arrows in the long run.
ROB - camping, although once Ike's in it's good, so I could see it even. DACIT stuff with the Gyro, though that doesn't figure in much. It more comes down to how long it takes ROB to KO Ike compared to how long it takes us to KO him.
Yoshi - did you watch the Yoshi-Ike crew battle, that's a proven even matchup with the best of the best from both sides playing and showing that, you can't give me ANY argument against this one. This was the weakest claim on my list. I still feel its +1.
PT - that's a +2 for Ike, you want it lower??? Fairly sure it said +1, though I might have read it wrong. Should be +2.
Mario - fireballs and caping recovery/jab1, even is fair. Even? It should be +1 for Ike. His FLUDD doesn't stop us enough, the cape is worthless against a reverse Aether, fireball is fairly worthless, he's horribly outranged, and he's not KOing as soon.
Jiggs - we just went over this with San Indeed. Should be +1
Bowser/DK/Kirby - no idea what these MUs look like
