@Xypherous. Why Titanic Hydra is going to fail.
Tiamat -> Ability user item. Hydra -> Ability user item. Titanic Hydra -> Auto attacker item?
Just how many high health auto attackers are there in LoL? You have Shyvana.... and ... Shyvana? Even Olaf tends to use abilities more than he auto attacks. Even Darius is having all his attack speed removed in the rework.
You really missed the mark on this one. This is basically gunblade all over again, an item built specifically for basically one champion.
In order to use Titanic you need: A large health pool. Attack speed already in your kit (or at least the ability to multi hit like Shyvana.) You need to use auto attacks for the overwhelming majority of your damage, or Hydra will deal more damage. You need to be melee. You don't do enough damage on autos that Hydra's AoE lifesteal would be better.
Seems niche.
Waveclear at last... hehehehuehuehuejajajajaHAHAHAHAHA
, tank
can all make use of that item. To different degrees of success, but it's actually a decent juggernaught item.

can find some use for it.
, it still gives him a W reset and it'll scale even harder with his ult activated.
