They did remove bunnyhopping - back in teh v1 to v.1.12 days people were macro spamming the dive and jump all the time. Remember a couple of clan matches where the entire enemy team (can't remember who, but they were german) were doing this.
They 'patched' this so that jumping detracted a lot of stamina, meaning you could do it a couple of times but then without stamina you wouldn't have the lateral movement to avoid stuff.
Additionally it's a hell of a better use of stamina to run quickly from point to point than to priovide a couple of seconds of jumping

The people that complain about bunnyhopping simply don't understand the terminology. It would be like me complaining about the current state of C4 lobbing

(if you don't get this in the older versions could jump and throw c4 almost like a manually detonatable grenade)
