[Item Suggestion] The Last Testament

Item: Last Testament: +100 ap, 20% cdr.

Passive: After a small delay upon death, freezes cooldown reduction [0% cooldown reduction], you can cast abilities that were not on cooldown before death but only once. Passive lasts until being unable to cast or channel abilities for 1 sec.

Example: Annie buys it, to prolong her life up to 4 sec, 1 sec R, 1 sec Q, 1 sec W, 1 sec E. She creates a "Zone of control" with tibbers on death so you have to escape it.

Example: Karthus buys last testament, it prolongs his life by 5 sec. 1 sec Q, 1 sec W, 3 sec R. Before karthus had ult but was unable to use it due to having only 2.9 sec of passive left.

Example: Nunu is a useless champion with 100% lose rate, he can now channel his ult without being useless.

Example: Katarina presses R after death. Maybe nerf her so there is a small delay after death like 0.5 sec.

Balance: This is the most balanced item ever that is gonna to make mages viable. Broken fizz can kill you in 1 Q [2400 dmg] without any skill or rengar with 1 R [only 2000 dmg, you should buff him]. If fizz had to press 2 buttons instead 1 the game would be more balanced. Why rengar has to press 2 buttons when fizz had to press only 1 ???

The game is binary, Fizz just flashes + Q without ability to fight back. Why cant i cast any of my abilities while dead ??? is this a bug? So i have cooldowns to use, and i cant use any ability just because binary jungle fizz plays the usual glass ap build and got a 20min buff from Rift Herald ? Magic resist items dont work, Fizz stays on the bush and everyone daring to leave base gets a 2400 Q. You might as well go afk you will never get a single minion. Your team has 0 chance to attack him as he always has E [which he doesnt use for damage].
