I actually like the idea of the eternals and am hyped for them, but feel like they are missing an actual reward for your achievements. The advanced mastery emote is nice, but it doesnt feel satisfying at all. The impact on the mastery icon feels too little in my oppinon.
Maybe make it, so that after a certain amount of achievement points, your mastery 7 emote turns into an epic version of it. something like the eternals statue. (They look really epic)
Something like that, so you can showcase your achievements better, if you manage to reach certain heights.
Right now the rewards feel lackluster.
