I don't really mind it, but going back awhile ago I tried to get a saber throw implemented myself using a similar system to the staff boomerang but instead of warping you it did damage. The reason why I stopped was because when I talked to Snk about it he said it was not possible as something about it caused too much lag, probably everybody's clients registering the throw and then having it track your character movement when it comes back to you.
I'm not a developer myself so I wouldn't be able to script something not currently in the game, and as I told these guys I didn't want to distract snk, who is busy working on countryside just to have him script an additional feature for an item that has been around for a year, JUST so these single saber users get their excuse to have an open/close ability on their saber.
Maybe before these sabers released, these features could have been cool, but right now I don't feel it is a priority to waste our scripters time working on a feature like this, when it will lose its novelty within a month. Especially as dual has been out for a year and single 2-3.
