I disagree. We already have /j and /back, plus, the VIP and VIP+ ranks are no longer available for purchase, so only we + the staff team would have access to it.
The point of having /fly for only 30 minutes makes it seem more like a trial period every week or so, except you can't buy the command for the rest of the week, and builds aren't worked on only 30 minutes every week. As I stated earlier, we already have /j and /back, which is more than enough for builds.
