I never expect it to fix the long term problem, hence, it shouldn't be idea for mages or anyone who activatly goes out to buy mana items.

Hence, I only suspect supports to grab it to aid their Carry. Late game, the support will either use it on themselves, the carry, or top laner. That's about it.
