New Assassin Item
Most assassins are failing to assassinate their primary target.
Even though I understand Riot wants assassins to wait for the right moment to go in to give a 100% guarantee on an assassination, that rarely happens because the AD carry will usually be protected so you will have multiple moments that give you something like a 60% chance to kill the AD carry.
As a proposal, how about this item?
Death Minister- 3300 +70 AD +65 AP
Passive: Grants 10% CDR Passive: 15 Magic Penetration and 20 Lethality Passive: This item is untargetable. Active: Select a target. If a target is selected, they will be marked and a passive, Prey, will be channeled for 3 seconds, and lasts for 15 seconds. Unique Passive- Prey: If the target loses health from you, but they do not die, you get a reset of all of your abilities and actives. Your damage does 15% than it is supposed to. (70 second cooldown) Unique Passive- Fatality: Your next ability ignores 10% of their armor and magic resist, and does 40 true damage. (40 second cooldown)
This item isn't completely useless if you succeed to kill your target, is usable by every assassin, has good stats, isn't abusable, and helps solve the problem, but it might be used by other classes.
Marksmen- I'm not sure about these guys. Divers: I'm not sure about these guys either.
