Jax got a mid scope update and then a couple months later an ASU, which essentially means he got a VGU but with a delayed V
At one point last year we were actually considering shipping both the gameplay changes and the visual update component at the same time. It looked like it'd be quite a while until we could line both up though, so figured in this case we should just get the gameplay shipped since it wasn't dependent on the full visual overhaul (unlike most VGUs, where kit changes won't work with old model, anims, VFX etc)
