Hextech GLP on supports
It seems to be one of the least used mage items, so what about running it on supports?
The Ice Gun thing. Was playing Janna a waifu of mine and thought that I needed more up front mana and not regeneration. My build at the time was Eye of the Oasis (Sightstone + Coin line), Boots of Mobility, and Ardent Censor. We were ahead, so I thought I could get away with getting redemption or locket a little later and not getting Mikael's since I'm complete crap about using that item. I've tried it on Nami and Lulu to some success before, but that was before the new items.
Any thoughts on the item on supports? Good stats (AP, Mana, and Health), good active for peel or engage if you're a champ who can engage well or have a team that can follow up. Only issues are that it's expensive and takes up an item slot potentially used for something else.
