I underlined the changes that were needed

On other changes - goddamit, they svck. And do that hard.

Jaw needed a nerf - it was ANNOYING
The DSG was annoying.
Kvolt was bad - now its propably better.
Air stomp is twice as usefull now! (0x2)

Other stuff - well, guess what? A lot of good players will ragequit, 'cos they dont know how to play the game now. And the nubz will continue to whine 'bout someone beating them.

Im both hands for re-balancing. But changes such as these work only in
A: Big projects (like WoW)
B: Games with huge balance issues.

I am sad about ltag - that shouldnt have been buffed - its pure spam. Happy about weapon pro. But hoping they fixed retriever not leveling/resseting.

Isn't this the list of changes from the 1.4 patch? Anyways, lol if these changes are true. The lol-tag is already bad enough in crash site.
