Still no use for BEs?

hi,

I am inactive for a long time now and wonder if there is still no use your BEs?

I have so many of them, I already got all the champions and I quit the game because there is like nothing to grind and ranking as well is also not fun because of all those ELO boosters and smurfers around. Usually, I am hard stuck platin for 3/4 of the season and when the elo booster are done, suddenly no trouble in rushing to diamond anymore. So I had/have like no motivation in playing right now.

So, I wonder if there is still no other use for BEs like getting skins (like you can do in HoTs) or if there were plans about someone may know.

greetings
