Heh. I know what you mean.
I mean, I'm aware of the fact that Sheik has a lot of potential. However, Zelda, I think, may have some potential as well. If people really think that Sheik alone is already in High Tier, then I wonder what people would do if someone utterly ***** with the tandem.
All 3 versions are, in my opinion, underplayed and underrated, especially though Sheilda. I can't even begin with how much potential the tandem has, so I don't understand the players who only play one side of her solo.
I mean, I know the whole "I can't properly control Sheik/Zelda"-part first hand since I have played only Zelda back then because I couldn't play Sheik properly. You're not forced to switch, so people are sticking to one. But you're still not going all out if only playing one.
Sheilda is - without a doubt - the most underrated character in the whole game.
