Ravenous vs Titanic on Fiora
I can't seem to get my head around this idea.
So far, I've done some math in terms of 'end game'. I'm still working on how early game works with planning out for 
but I do have a list of items that go with her whole kit, and her role, in general.

But what I'm stuck on is, besides 20% attack speed runes, 265 scaling HP runes (with 45 HP from mastery), 34 scaling magic resistance runes, and the like...
vs 
Armor and MR wise, we have 158.5 armor and 157.4 magic resistance
HP with runes and masteries and items 'currently' would be 3605 HP.
current total AD with the 5 items would be 246 total AD with 130 bonus AD for abilities.
and lifesteal would be 15% (17% from 2% masteries) with 40% CDR from
.
The only thought left would be the difference besides 100% health regen increase.
means that your lifesteal is at 39%, 321 total AD (205 bonus AD), and still at 3605 HP. Meanwhile, you're attacking enemies in a circular area with each auto attack, and have a burst that can come up with a Q, E auto, item burst, second Auto.
means your lifesteal is still 17%, with 296 total AD (180 bonus AD), +45 on hit physical damage, and be at 4055 HP. Your auto attacks hit in a cone formation, relying more on
to heal from 5% cone damage and 15% on-hit physical damage. But the single target burst with one auto attack would be 445 from
, 296 from total AD, and most likely 200 from
.
But what I'm wondering about is the practicality of either type. I hope to get some feedback on all this number crunching and theory crafting.
