So support is my main role and I've done it for a lot these past month and while I understand why supports tend to stick to Aura items and wards, What about Aura based AP items? I've looked at a few threads about this that was dated months ago and the reasons why people said no to it was "AP items to expensive" and "Items like Aegis and Locket etc are more beneficial to teams"
So I thought about it and what if you base your entire Runes/Masteries to getting money and buying a lot of ap items that help the team? So let's say...
Maybe Magic Pen Marks?
Flat armor seals
Magic Resist Glyphs
Making sure you get all the gold based masteries, especially Pickpocket
Flask, +2 Wards
Boots +2 Health potions, +1 Ward
First items to get:
Boots (if you have not started with it)
Kage's Lucky Pick
Then get Tier 2 Boots (Tabi/Treads/Ionian/Sorcerer Depending on the support champ)
Upgrade Lucky pick to Will of the ancients
Buy another Lucky pick
Upgrade that to Shard of true ice
So Mid game you'd have:
Will of the ancients
Shard of the true ice
Tier 2 Boots
Get Abyssal Scepter, and then sell your flask
Finish off with a Rylai's Crystal Scepter
So your final item setup would be:
Sightstone (Which if you feel you wont need it, can be sold for any other AP item)
Will of the Ancients
Shard of true ice
Tier 2 Boots
Rylai's Crystal Scepter
So now you'll have 275 AP, 20% Spell Vamp, A active that gives an ally a blizzard that slows nearby enemies, Nearby enemies lose magic resistance and your skills slows the target. Not to mention your will of the anicents also gives allies spell vamp to, and since you have sightstone you have all the wards you'll need. So with all of that, plus your skills doing more damage and your heals will give more, I personally think this is a better choice then getting a few active items that only work 1 time per (60+ seconds) and some minor defense and regen.
I get that it's still expensive to get all of that, roughly 11.4k gold but if your getting decent amount of assist, plus with your gp/10 runes and items and with the pickpocket mastery it shouldn't be to hard and it's possible to get this set-up as a support if the match reaches 30+ mins.
I know that this really depends on what support champion this is on. Since some champions have little use of AP (like Sona since ap only helps her damage and her 1 heal skill) But at the same time there's some supports that due very well with AP like Soraka with all her heals + damage, or Janna with her Shield + her CC skills (which actually have a decent AP ratio as it is)
I haven't really tried to get this set-up but I wanted to for a bit and now that I had a time to think about it as I was writing this out, I believe more people should start doing this. If your going with a support that has extremely low AP ratios, or really only good for certain buffs that uneffective with ap (like sona's armor/mr/movement buffs) then sure stick to the usual defensive aura items. But I think when your using a support champion that scales with AP pretty well, or has good damaging CC or good heals then I'd suggest looking into this build.
Please let me know what you all think and if I missed a nice addition to an AP aura based support build that you think I should add.
