Mage Rune Question

[quote=MrPistachio]I just bought a champion pack so I'll have plenty of champions to hold me over for awhile so I won't have to use IP, and I want to start getting my rune book full for when I get to 30. Now, I normally find myself playing mages, so I'll fill a rune book for them first. I figure the runes could pretty much be the same for all of them, AB, Mp5 and Penetration, except for the few that might want CD reduction a bit more, but oh well. [b]I can't figure though what quintessences I'll get though. Guides I've read are controversial to eachother with some saying Fortitude and some saying Potency, and I'd like to ask what others think.[/b] Thanks in advance, Mister Pistachio[/quote]

[quote=Lugignaf]90% of the time, potency. Flat AP is almost always best on every AP champ.[/quote]

[quote=Bryun]Yep ^ Potency is the way to go. Unless you're the type that doesn't do too well early game, then Fortitude.[/quote]

[quote=PsiGuard]Potency for a stronger early game. Fortitude for a safer early game. It depends on the champion and the player. Some champs (or players) can't make good use of the early ability power, and for some it establishes lane dominance. I'd say go with Potency for Nukers. Get Fortitude if you want to be more defensive or have a champion with a weak early game.[/quote]

[quote=Searz]Flat AP quints, MrP marks, MP5/lvl seals and AP/lvl glyphs is the standard AP setup.[/quote]
