I meant to type about this around the time the article '3 Reasons to choose a top tier-by omni' appeared on the smashboards news. Got busy, then forgot about typing some thoughts I had about Geno and the 'Meta', but now here it is! Lol. (Oh wait, I went to find that pic that show-cases Geno's very classy Specials and the clever charge system. I'll be making references to that.)
Okay, I want to talk Geno's Whirl special, and the mechanics/properties it has when hitting the opponent. Shield Breaking property- If the opponent hasn't perfect shielded, but rather is in shield, and you land the Geno-Whirl-timed-hit it should practically take out the opponents shield. For a second, look at Marth, his Special can charge in the air, strike with power, bust a shield, has like no end lag; so asking for a shield bust plus in the Geno's Whirl move shouldn't be much of an issue, especially since it needs charged and probably needs the correct spacing. Also I would like it to have a meteor effect if the timed-hit is proper.
If it is a lot to ask for, it could be balanced by letting the move ruin your air-recovery/maneuverability if used in the air. Similar to how Donkey Kong doesn't recover if he uses the Donkey Punch off the stage.
