I've always been partial to getting adren and slamming spacebar alot anyway. Works much better than the gliding method
Gliding just has an eventual slowdown - the main good thing about it is you'll regain energy inflight, which you'll need for future takeoffs/speedups.
This of course all goes away, and you can just mash your jump key and/or have an alternate triple jump handy for those rocket-like boosts. Don't even dare blame that on scripting, as you could mwheel the same thing or use any other form of hardware +jump spamming.
Imo, the same thing as with the pistol needs to be done of they want to make headway on balancing the lerk - a limit on flaps/second. Also possibly a vertical rise speedlimit, as thats pretty insane as well.
And even then, the Lerk should not necessarily be flying for free. Cheaper, sure - but free is a tad bit lame.
Anyways, off to find a server and see if I can get a good demo of what Lerking is like right now (basicly its vertical masturbation+random biting = kills by the boatload).
