These Star Guardian missions feel awful

If anyone has played onslaught, then they would know how difficult it is.

Onslaught is harder than Doom Bots and yet there are missions to complete on top of it MULTIPLE TIMES. We wanted harder missions and these are difficult so thank you Riot for that. But there's no incentive to complete them - nothing to say "you're a beast at this". Oh, here's a champion shard that isn't very useful if you have a majority of the champions and a ward skin.

Thus, the missions don't feel worth the time honestly. I liked it once. Got bored after four or five trials.

TBH, if you made the mastery emotes a reward - then that's possibly a good incentive. Oh wait - they're only available if you have an icon which we get thousands of and temporary
