It may be a hoax but apparently Valve are considering some of the suggestions as they are quite good.
it's a hoax.. it says so itself at the bottom of the poster. It's an old hoax, at that..
I couldn't care less what unlocks they provide, all I want is my cloak to recharge at dispensers/fill at the spawn cupboard!
I hate waiting around for 30 seconds, doing nothing whilst my cloak recharges!
A workaround if you are near enough to the spawn is to instantly switch back and forth between another class. Instant cloak refill.
