My thing with zen is that discord is all he has. Nerf it in the wrong way and you might as well switch to kirko entirely. 40 bs, 120 hs vs his non boosted 48 bs, 96 hs [60, 120 with discord], smaller hitbox, way more mobile, suzu.
One idea that i just hate are ones that remove discord and give him a mobility option. I find it boring and he still has a beefy hitbox. At that point, i’d rather they make him stand up, walk around like normal person, scrap his entire kit and give him a new one from the ground up.
