Possible Solo Queue Changes
In my opinion, most of the frustration with promotion series comes from the ease of demotion relative to them (i.e I can go on a 5 win streak after being demoted and find myself being demoted again for losing a couple in a row). A couple of changes to make promotion and demotion more equal would help relieve this frustration.
-
Remove innertier promo series- Rather than having to win 2/3 games after already reachiing the top of a division you would simply need to win just one after reaching 100 LP. Considering demotion occurs after losing just one game at 0 LP this more fair than the current system as promotion is the converse of demotion.

Demotion Series- As for intertier promotions, I believe the current 3/5 win promotion series is fair as it current stands. Demotion, however, could use a change to make it more of a converse to promotion. Just as you activate a promotion series upon reaching 100 LP at the top division of a tier, you would activate a demotion series if you reached 0 LP at the bottom division of a tier.
