The new essence reaver might be too strong

Essence Reaver New build path: B.F. Sword + Caulfield’s Warhammer + 800 gold (3200 total) Cooldown Reduction :: 10% >>> 20% [REM] No longer grants critical strike chance [REM] No longer grants additional crit chance based on critical strike chance. Mana refund reworked: Now grants 1% of missing mana on hit. [NEW] UNIQUE Passive: For 8 seconds after your ultimate, gain 30% attack speed, and basic attacks refund 20% of your remaining non-ultimate cooldowns (30 second cooldown).

Explain: It's well balanced for ADC (Maybe a little broken on lucian) but has too much problem with other champs (Expecially Fighter but not only that). < Watching a fiora that press R and then Walk around mark with no CD on Q (:/) or Master yi that will just get 5 auto to get again is Q (Considering his passive wich mean only 4 aa + guinshoo it will be down to 3 + his ult alredy give CDR and Attack speed "This Sound a little broken"). About Riven In the wrong hand it will be bad but in the hand of a skilled player it could become something Dangerous to watch ("Literally she can walk on you for 8 s using only her Q (Q+Auto+Q+Auto+Q+Auto+Q+auto.....")), Jax cannot be killed in a 1v1 in my opinion but it's not better than those three (It will leave really low window of outplay for a 1v1 auto vs auto because his E cd). Tryndamere... Honestly tryndamere it's the only one that this item work in a good and wrong way.... If he crit a champs he will get 2 cd down + 20% of the item and this will make him the new spin to win because he need at least 2 auto for benefit of no CD on his E (Urf trynda?) but at least it wouldn't give too much and can be easily shutdowned without problem. Kled literally has no CD on his W and his Q so you just can't escape. Even with a 10% instead of 20% can be too good with some of em.
