I've seen some people use the Tourney mode, but that's irrelevant, as I wasn't referring to this to begin with.
For Glory is not meant FOR tourney players, it just happens to be something that will benefit them, as a training ground. As many people have already noted, there are players who don't enter tournaments, but happen to like playing with items off and what not. This includes myself (as tournaments for Smash don't exist where I live). For Glory is for people who want a quick online game with a more raw ruleset. Nothing more. For Glory will be impossible to use as a vehicle for tournaments, but it will be a good training ground for people who want to participate in tournaments.
Again though, this has nothing to do with the post of mine you quoted. If you want to discuss For Glory Mode, there is more in-depth discussion of it here:

This topic is all about whether or not local tournaments will be a thing for the 3DS version, and I personally don't think they will be after the Wii U version comes out, because 3DS players can simply compete in Wii U tournaments, as the characters all play the same in both versions. Any practice done in one version will carry over to the other, and setting up streams for the Wii U version will be a lot easier. Online tournaments on 3DS will still be a thing, but local 3DS tournaments will be redundant, unless we consider Smash Run as a tournament vehicle, and I for one think it's worth experimenting with.
