Thx for your constructive criticism .....yes there's a point in Greater Mark of Hybrid Penetration in combination with Spellthief's Edge but especially the almost "pure" ap build shoul always avoid to autoattack, becaus it gets you out of psition, i only do so if i'm sure the enemey can't counter react anymore to my AA'S due to them beein half hp/zoning etc. Eventually you won't profit of the runes in mid to late game anymore becaus your goal will be to stay in the backline before, during and after teamfights only in certain situations you'll be able to safely autoattack.

The Iceborn Gauntlet thing yes it's being erased soon i think.

For sure I'll have some overlooks to improve the visual part of the guide like the "bigger rune icon thing"

But i don't think i gonna add warding etc, the general support stuff but i think i'll do a general support guide which i'll use to refer to in this case ;D

Starting Items there...if you are going Spellthief's Edge, that means you'll be AAing alot to get the gold, then your marks should be greater mark of hybrid penetration. Also, mention Doran's Shield start, it is a good item to makes you be tanky in the laning phase.

Iceborn Gauntlet is not good on Xerath, don't mention it.

In the Runes chapter, the runes should be "Greater" instead of Glyph of Magic Resist, Mark of Magic Penetration, Glyph of Ability Power and Seal of Armor.

Explain alternative masteries, like 0/9/21 or 9/0/21 for supports.

Add some more chapters in this guide like Warding and Objectives, Synergies, Match-ups, Teamfights, Laning etc.
