What Do We Do With Rylai's?

So Riot has decided they want to narrow Rylai's Crystal Scepter's users by defining the item as being good for a class. So I'm going to have a discussion about the three Mage subclasses and discuss the pros and cons of each. I will also suggest a final build for a Rylai's for each class. Vote for your choice in the poll!

1. Battlemage This one seems like the obvious choice. You can't instantly kill enemies, but you also have to be in the thick of things to even damage them, so if there's a Health AP item, it should be for Battlemages right?

The con is, most Battlemages actually have pretty decent CC already, adding a slow might just make things worse for the opponent.

Suggested build: Giant's Belt + Fiendish Codex + Ruby Crystal + 900 gp (total 3200) Stats: 600 Health, 40 AP, 10% CDR Effect: 40% slow for single target spells for 1.5 seconds. 20% slow for 1.5 seconds for all other spells

2. Burst Mages The argument to be made here is "Hey! Don't fucking delete ANOTHER Needlessly Large Rod item!" Slowing enemies might not be the typical playstyle of a burst mage, but perhaps the price increase of Rabadon's has left burst mages with too few items to rush.

The con of this is that unless you're an assassin, you probably won't get away from a burst Mage with this item. But maybe that's the way it should be?

Item: NLR + NLR + 800 gold (total 3200) 120 AP Unique Passive: Dealing magic damage to a champion slows that champion by 50% (+5% per 100 AP) for 1.5 seconds. (60 second cooldown)

3. Artillery Mages The main pro of this is, if we force it, we never see the item again because there's maybe three AP artilleries in the game.

The con is that if you get hit by poke, you're probably going to get hit by more poke. But maybe that's fair, since artillery mages don't have infinite mana anymore?

Item: Crystalline Bracer + Needlessly Large Rod + Amplifying Tome + 965 (total 3200)

80 AP 300 Health 50% Health Regen Unique Passive: Damaging an enemy champion with an area of effect spell slows that champion by 10-60% based on how far away you are from the target. Triggering this passive gives you 100% bonus health and mana regen for 5 seconds.
