EDIT: I am currently running 15 ad (ad marks and quints) 40 hp (5 hp seals) and (4 armor seals, 9 armor glyphs)10 armor on my main page. My page with mr (for backup) is 9xflat armor seals, 9x flat magic resist glyphs, 9x ad reds and 3x ad quints

As Season 4 is picking up speed, I am predicting 6 armor penetration reds, 3 flat ad reds and flat ad quints to become the standard for ad carries once again. These runes were seen as optimal at certain points in time and indeed, it was not uncommon for certain players to run armor pen reds AND quints. As we... Read More
