I quit because:
-Demomen jumping died long time ago, when Valve broke some stuff about the sticky radius and all those things (less radius explotion, less units = less speed, etc. That stuff has never been fixed).
-Ullapool speedshots are gone, like quickie bomb airpogo and probably loose cannon, so demomen trickjumping will be less creative.
-I did my best with all demoman weapons, bringing to you new techniques to impress people, nothing left to do.
-I get a bit tired.
Maybe if Valve decide to give back the demomen jumping of 2 years ago, probably i´ll be back. But now, demomen jumping still dead for me.
And yeah, classic Valve, trying to repair 1 thing, and breaking 20 at the same time.
