Reading this thread brings an image to my mind: A guy with a wooden stick explaining his options vs two guys with machineguns and infinite ammo that also have the high ground.
Anyway, I love Jax, and Pumped Up in particular. But if the Gm player is not trash, this is not even a matchup, it's a rape, no matter how you look at it, specially after stupid loss of ex bf2 armor (meanwhile Tremor keeps armor on a very similar nature move that he can cancel to become the closest thing to an armor launcher. Good job nrs). Even Balanced pretty much rapes Jax now, that's where last patch left him.
Things pointed out in the thread (although some are very hard to perform with consistency) will be useful though, to those that are masochistic enough to face the struggle.
