First of all Jayce didnt really get Nerfed in 3.9, it just makes maxing Q/E for both his melee and range damage less effective but its still worth it to be honest. His E in melee form does massive damage when you focus on speccing it alongside his Q, it gives the most damage and puts you ahead in fights that way the extra DPS from a specced W isnt needed.

If you build the way the majority of Jayce players do and synergize a BC with CDR boots the nerf isnt even noticeable. On PBE his "nerfs" are honestly just a power shift. It now goes from massive burst damage from maxing Q/E to more consistent damage throughout his levels, BUT the removal of the mana on hit in hammer form is a GIGANTIC hit to him. Thats the only thing I call a real nerf. now his laning is much weaker and he is forced into starting faerie charm with points in meditate to even try and keep up his lane sustain.

The reason why the Tourney server is one patch behind is for stability and for familairity, so what if Jayce can spam 2 more Q/E combos in cannon form prior to a fight? Deal with, its always been like this. If they dont want that happening they need to ban him. Jayce is a really strong champion and thats one of the landmarks of his kit.
