The only reason I even rank up 5 stars anymore is for the level up event unless I happen to pull a new release good champ I don't already have as a 6 star otherwise I don't waste resources on 5 stars anymore much less 3s
I Rank everything eventually. Why skip out on Level-Up in-between large Rankings? You can hit Milestones cheaper. Besides, I've never sworn off Ranking anything, whether I use it at the moment or not.

Unless needed for side quests where spots are already limited but you must use a certain champ in your team.
For that matter, every 4* I own is at least R3
Why? For the level up event! Need those free L1 revives
Now I'm ranking up 4* as well. Much harder mission though.
3* get maxed over time for lvl up Event
4* only to rank 3. Some to r4
