Meditation made a lot of junglers possible.

Without it, I can't even clear once without running out of mana (unless I get blue), even with talisman and mana restoration from Sorcery.

I know you hate it when champs go out of the role you wanted them to be in (Lulu mid/top for example, which I do enjoy), but can you look at junglers (in my case, Poppy and Ornn) and adjust mana costs / passive regen / talisman's mana regen boost (not all of those, but maybe one or two)? Even on champs intended to be junglers though, like Kindred or Eve, I run out of mana really easily if I have no way to restore it.

The mana band thingy from Sorcery doesn't cut it, either.

Even when I build mana items, their regen is just so low that I still run dry really easily.
