A small hint for mage supports at botlane
If you're buying an aether wisp item (Ardent, Ludens, etc), dont bother with tier 1 boots early to mid game. Instead, get The aether wisp. Chances are you'll sit on tier 1 boots until you've purchased your main non sightstone item ( which usually involved aether wisp).
Idk... I observed many mage junglers doing the same due to unreliable gold source.
