Talon's passive
Mercy:Talon deals 10% more damage with his basic attacks to any target that is slowed, stunned, immobilized, or suppressed.
Talon's combos typically consist of without tiamat E+AA+Q+W, E+AA+Q+W+R, R+E+AA+A+W, and E+Q+R+W.
In these combos your AA and Q isn't fast enough to get passive from the slow on your e and since W is after both AA and Q you won't be getting the 10% bonus from passive. Now you could get to use the passive if you have cc from a ally, but that makes talon more team reliant where he shouldn't be at all. Plus since he'll be in the backline in team fights your teammates will rarely if at all be there to assist you with killing either the adc, mage or other priority target. Making your passive effectively worthless.
Which is why it should be changed to better fit his kit. A change i'd recommend is to have the passive work on all abilities instead of just AA. The bonus itself could be lowered or have a scaling, but this is a better alternative to never using it.
