It's just going to hold someone back from getting better in the long run since players tend to shape their strategy completely around trying to land it. No oki. No pressure. It's in the same vein as spamming shoryukens. It might win you matches against players who don't know any better but it really is just holding you back. People are free to do it all they want, all I was originally saying was that I dislike it.
And sure, it's possible in Guilty Gear and other FGs as well, but what are you going to do with it in GG? The gravity, damage scaling, and pushback kick in big time. If someone wants to try and do 2PP then super I generally would welcome the waste of meter, since dust moves and f/rcs are generally a better use of your meter for most of the cast. Personally, I use D tandem top too much to waste meter on a super.
