Very nice. I do recall those names from the Brawl era. ^-^
Those were what made Ike a competitive threat in SSBB, yes, and we will miss them. Of course, that does not mean there cannot be any new discoveries for Ike in this iteration. The Wii U version will surely open more possibilities, thanks to more optimal control options, such as the C-Stick.
Ike does seem to be given some of the better customs, compared to many others in the cast, which address some of his problems, like recovery. His placement on the tier list would probably rise considerably if customs are factored into the critieria.
