So, according to the Patch Notes, JJs got their long needed redesign, with thrust now being linear, meaning the days of the single JJ poptart should in theory be over, and the Mechs like the Griffin and SPD-5K with massive numbers of JJs actualyl see more pronounced benefits for their use of max JJs (though for those who actually knew how to use them, near Max JJs were ALWAYS a good thing). Further, Jjs and their airiel twist rate are supposed to hvae been changed by Class, so that Lights are the same as ever, Mediums a little slower to tiwst, but Heavies being notably slower and Assaults postiviely "glaicial" to eliminate the instatwist Assault Poptarting.
Since I tend to run near max JJs anyhow, I haven't noticed much difference, except in my Highlander, but I spend way more time in my Mediums and Ember, so I can't say for sure. Have seen notedly less Poptarts in my matches for the last 24 hours, but dunno if that is just luck, or if the JJ nerfs actually hit them where it hurt. (hoping for the latter).
Would be nice for those touting the "Church of Skill" to have to "L2P" finally!
