Guild Wars 2

I tried to find this in the forums but I didnt…
However, when you throw one of the rocks/crystals mentioned in the title there is a bar appearing “loading up” to max and if you drop the rock when the bar is about 80-100% filled up, the rock will be dropped and thrown away at the same time dealing damage and you can repeat the process.

I guess it’s just a minor bug but i wanted to let you know so you can fix it.

Edit: This is inside the Fractals of the Mists dungeon, Fire fractals and boss fractal.

This bug still exists and it might have to do with engineer kits, instead of what I said earlier with dropping the rock at 80-100% you equip a kit. I asked some friends (non engineers) to do it and no one was able to do it but me.
