Rune costs are not tuned correctly at all
So a Tier 3 Glyph +0.27 Health Regen /5 secs costs 850 IP http://i.imgur.com/NjB8bjM.png
While a Tier 1 Seal +0.35 Health Regen/5 secs costs 5 IP http://i.imgur.com/4vULpKt.png
Now I know they are different in the fact that they are glyphs and seals but I mean wow Why should I even use IP on the Glyphs of Regen? The seal is 131 times better than the Glyph. Sure Glyphs are suppose to be weaker in those stats but I mean come on!
