Respawning animations
Having bought Braum, this issue came to my attention. All recent champions have elaborate respawn animations. Braum jumps from off-map, Vel'Koz comes from a portal, Jinx falls from the sky, etc. Everytime , because players of course have no need to stand waste time lingering, these elaborate animations gets interrupted and it looks off.
Why not start respawn animations ahead so that they end in sync when the timer itself ends? While a minor thing, it would look a lot more clean.
