It's okay if they keep it but it seems like another think like L-cancelling that you might as well almost always do, so it'd be cool if there were a way to make it just automatically do it for you. I know, you're all going to hate the idea, but I don't really see the point in making people bother having to do this sort of thing.
There's a bit of difference between making offense faster with precise presses and a defensive technique that's only usable when you can't do anything else.
There's also a bit of difference between a 10 frame window and a 30 frame window.
Not to mention that there's a legitimate penalty for not attempting to tech at the appropriate time (ie. not being able to tech until the 'frame-penalty' has run its course). I can understand why some think that L-cancelling is a bit of an unnecessary hurdle in the grand scheme of things (since it's something of a given already in high-level play). Teching, however, is indeed out of the question.
But... surviving is more fun!
Also this, lol. I've actually had a number of tense moments in Smash where, had I not been able to tech appropriately, I would have been finished. It's a skill that, admittedly, takes time to execute effectively and consistently, but that's the same with all proper techniques in competitive games (fighters or otherwise). --- http://i.imgur.com/qgqVy.jpg "Don't wanna know...where the sinners go..."
Perhaps the way to go would be to have some walls techable and some not. That could both prevent some walls from being stupid while keeping reasonable wall teching as a part of the game. That and open up wallbounce combo opportunities. --- http://puu.sh/2gpqf Wasting meter since '08
