Greetings! I finally reached level 20. In other words, I can now buy tier 3 runes. Before I do so, I would like some help choosing which ones should I pick (Because some are quite pricey..) What's your opinion on them? Which ones do you use and would recommand? If it can help, I mostly play melee characters. I don't play mages much... So yeah, spellvamp and AP items won't be that usefull for me :) Thanks!
I'm not going to give you a direct answer because what you need varies greatly between roles, and sometimes drastically even between two similar champs of the same role. What I will do is give you a resource to look through so you can make an informed decision;
Check out builds for the champs you want on Mobafire, and see what the highest rated guides suggest most often. If all else fails, get MR Glyphs Armor Seals AD Quints and AD or Armor Pen. Runes.
OK the runes you wanna look at are:
Armor Quints, flat/scaling Armor Seals and Armor Marks in that order. All four are usefull, either to stack up, or to shift around and make room for other runes.
flat/scaling MR Glyphs There really are no better Glyphs unless you wanna stack on AP.
flat AD Marks, helps with last hiting.
maybe AP Quints, some melees scale heavily on AP, not sure what you play.
Also quite usefull can be scaling health and scaling health regeneration Seals.
You want Attack Speed everything
Then you are set to play AP xin and 1v1 turrets
It depends on what melee champions you are playing: Non auto attack based- 9x flat AD reds 9x flat armor yellows 9x flat magic resist blues 3x AD quints
Auto attack based: 9x flat ad reds 9x flat armor yellows 9x flat magic resist blues 3x Attack speed quints
These are just standard runes, you can change them to however your liking. Ex. flat armor yellows to scaling ones or health. I know that you said you don't play ranged champions, but if you ever play ADC go with the first one, not the second one.
Honestly I have a different rune page for each Champion I play. Mobafire is a great place to start to find useful item builds and rune pages. Look up your Melee Champions and build a rune page based on what you see. If you think you are familiar enough with the game to tweak the rune combinations, then do so. Once you become comfortable with all the rune builds on your Melee Champions and continue to see good in-game results, I suggest learning to support and just repeat the Mobafire process when doing so.
*>*Note: When looking for any builds on Mobafire, make sure they are credible. For Example: My 
is based off of Cloud 9's rune build and it is effective in game obviously, because it was submitted by an LCS Summoner. I suggest, for best in-game results, that you only make use of the builds that are Platinum Certified or higher.
Best of luck and I'll see you someday in ranked!
Minimum requirement;
Marks: AD, Hybrid Pen. Seals: Health Glyphs: MR Quints: AD, AP, Armor
Plan on;
Marks: AS, Magic Pen. Seals: Armor Glyphs: AP Quints: Life Steal
For specialization;
Marks: Armor Pen., Armor, Crit Chance Seals: Health Regen Glyphs: CDR, Mana, Mana Regen Quints: MS, AS, Health
There are a few champions that can have specialized pages just for them, 
and 
for example.
You want a minimum of 3 pages; AD, AP, & Def. Constantly strive for more of them.
Well, with all that, I do feel like there's way more to concider and to optimize for each champs... I'll try to work something out. Thanks again for all that!
If you don't play mages, look to buy:
Marks: AD Seals: Armor/Health Glyphs: Flat MR Quints: AD
That's where you should start. The Armor/Health seals are a toss up. Some people say that health are better now and I've heard others feel that armor is still really good. If I were you when you have the time try both. Health will do you more good early game in trades and other stuff. Armor will do you better probably a little later on.
My best advice, though, would to start to narrow your champion pool. Pick your favorite champions and then hone your rune pages around them. I don't know if you plan to try ranked, but a small champion pool will do wonders for you. I recommend at least picking one champion for each lane and then be able to play that in the least burdening way to your team (i.e. don't feed).
