Tiamat rework. It'll be melee-only, the splash damage is UNIQUE, and can be upgraded.

Tiamat

(Melee Only)
+50 Attack Damage
+15 Health Regen per 5 seconds
UNIQUE Passive – Cleave: Your attacks deal up to 60% of your Attack Damage to units around your target – decaying down to 20% near the edge.
UNIQUE Active – Crescent: Deals up to 100% of your Attack Damage to units around you – decaying down to 60% near the edge – 10 second cooldown.

Upgrade:

Ravenous Hydra

(Melee Only)
+75 Attack Damage
+15 Health Regen per 5 seconds
+10% Life Steal
Passive: Damage dealt by this item works with Life Steal.
UNIQUE Passive – Cleave: Your attacks deal up to 60% of your Attack Damage to units around your target – decaying down to 20% near the edge.
UNIQUE Active – Crescent: Deals up to 100% of your Attack Damage to units around you – decaying down to 60% near the edge – 10 second cooldown.

R.I.P. Tiamat Twitches and Shyvanas getting easy pentakills.

In the case of Fiora + Ult + new Tiamat:

Tiamat + R, Fiora basically hits a larger area in exchange for not triggering the 500 damage in the splash at level 18. While this is kind of a trade-off - it also means that stacking Tiamats and hoping the enemy team is grouped up is no longer a thing.

And the case of Shyvana's Dragon form Q:

Tiamat has an internal proc limiter against different targets of 0.05 seconds - so Shyvana's Dragon form isn't going to Tiamat Proc 6 billion times any more and we might be able to add AoE on-hit abilities now.

So no more exponential damage now.
