ok well most new people to rank don't even know what runes they need . and by lvl 30 if you cant seem to figure out how to fill two generic run pages then you need to rethink what you are doing with IP
AD page

9 armor seals
3 ad quints

but as the OP stated about hp regen runes... you can have a mixture of tier 3 and tier 2
like use tier 3 on all the runes except for the hp regen runes and then get tier 2 for those til you get enough IP for them
also you have to make a choice of using IP on champs or runes...
people don't want to use RP (pay $$ ) so they use their IP for champs therefore they lack IP for runes
if you stop buying champs with IP til you get a few basic rune pages and just invest a lil $ in rp for a few champs ( like the bundles that give a handful of champs for like $10 )
I know people cant always spend $ I get that... I have bills trust me... this week at work sucked and rent is due ...
but you don't have to have everything at once...
riot has to have income to support all the things needed to keep the game running ... so by them kinda in a way forcing you to get RP for champs instead of using IP it supports the game...
fyi I have played since end of season 2 and I have only spend $325 on the game with buying RP for champs/skins etc and most of that was gifting to friends for whatever ... last two times I got RP I got a skin for a friend for her bday and I was kind and gave another friend on my buddy list a few champs for the holidays...
