So, his autoattack have up to 50% passive critical damage increase, deal max. health true damage, grant you a stacking AD / MS buff, and can reduce all of her cooldowns.

The basic abilities and the ult barely pass the 10s cooldown, have two forms to have their cooldowns decreased (Autoattacks and if the abilities critically strike) and all of them can critically strike, even if the damage of the abilities seems deplorable (Except Q), all of them still can deal up to three times their displayed value.

Can passivebly have Attack Damage, Attack Speed, Movement Speed, Critical Strike Chance, Critical Strike Damage and On-hit Damage, and activebly Tenacity, Damage Reduction, AS Reduction and another Movement Speed boost.

Perhaps the AS boost can I forgive, despite being an Hyperscaling effect, the champion doesn't get AS per level. Beyond that is but a walking ball of stats that only needs to attack (Not even to kill units or do a more understandable task, just to attack) to get them and depends too much of criticals to be efficient, which means that, gameplay wise, depends too much of luck.
