What no double jump?
How are you supposed to get away from the boss fast now?
He will always get you now due to all the classes except infiltrator being fast.

The double jump isn't the best, since it does a datablock change(in addition to other things) and has messed things up in the past countless times. It's real buggy. However someone I know has made another type of double jump and it works quite well, although I don't know when it'll be released, nor would it really redeem Runner in this case.
Rocketman, Detonator, and Firebug are able to rocket/stickyjump and jet respectively. Detonator is hardest out of those, but it's still possible. I personally think Infiltrator dies easier than the classes I listed since it only has a base movement and nothing else; predictable.
No seriously, usually whenever I see someone play as constructor they are the first to die because they can't get away fast enough, or their sentry is nulled by Medusa's attack.
Also isn't support the Healer's Job? And if runner will cease to exist than what will be the new fast call that can get away faster? Infiltrator?
Please don't violently attack me.
Constructor in my opinion needs a defense tool. Or something. The sentries are a mess for the most part, which I've spoken to Jetz about in the past. They generally need a clean up as a whole.
I don't think it would hurt too much to have another support class, but then again no one may play it at that point, because it's support. I believe the idea is that this new replacement for Runner would work together with Constructor, although I'm not sure on that.
On another note, almost no one says anything about Sniper. Sniper is even worse off than Constructor, while being able to snipe any boss to do a decent chunk of damage, the sentries have a huge blast radius, and don't need constant aiming unless the boss is at far distances. Something like a stealth tool for sniper, even if it's only 10s of being invisible would do the trick.
I'll end this with a note on Overweight: I remember talking to Jetz and that's how Overweight had a timed jump because of ModTer. What I don't know is why Overweight has increased fall damage. I don't really think it fits at all in the server. I'll take a stab and say this was because of the boss Ephialtes, because he had such a hard time with this class, so it had to be nerfed, rather than the boss buffed in a certain way. Along to go with that, for say the Bedroom, Hangar, Castles map even, the launch/jump pads are a pain to fix for Overweight, then it's still possible to accidentally kill yourself from the jumping.
Just my two cents and what I see in the server as of this moment and the past.
