Yeah, for those you want per level since they surpass so quickly. For a lot of runes though it takes a while for the per levels to surpass the flats and at that point I typically go with flat, runes make the biggest difference in early game.
When I bought runes since I only had two pages I set up one for general AP and one for general AD.
MPen reds
MP5/lvl yellows
Flat CDR blues
Flat HP quints
APen reds
MP5/lvl yellows → dodge yellows
Flat CDR blues
Flat HP quints
It's hard to go wrong with flat HP quints, 26 HP/ea at lvl 1 makes a huge difference.
