Who is the best leashing Champion?
I am a support main, and I have been thinking that there is no way to win any game in Silver unless your ADC is leashed peeled properly through any team fight. And since no one really cares about his team's ADCarry, I started playing champions that can leash peel as much as possible.
So I decided to play Tahm Kench more and more and found that the slow in his Q, and the devour with W is working pretty good, but sometimes it just is not enough. Is there any better champions or items that can help leash peel?

and
, many other tanks could also work. Also if you want something squishier then definitely
as the best peeler in the game.

. I do get Locket and Redemption as well. I might try FotM next time for more shield.

(Aggressive. Procs off Q and E.) [AP]
(Adds more to the aggressive. Basically a kill lane now.) [AP]
(If you need heals really bad and plan on building other HP items, go with this. It helps you passively heal and also affects your stoneborn pact healing.) [HP and your second mana regeneration basically]
(Also procs off stoneborn pact. This is completely situational and not meant to be built until mid-late game.) [Heals for even more if they haven't hit the target already.
(Anti-CC + AP +CDR)
(It's just funny to add more stuff to the Q. I wouldn't do this unless it's needed for whatever reason.)
(Anti-healing. Not a first choice and situational. Less than Liandries though.)
(Only if you want to make your E more successful at snaring. Gives AP and HP too. Slows do not stack.)
(If you have mana issues. I would sincerely avoid this though)
(Can help with armor. Gives AP. I would get if you use it's active. I don't use the active so I find it useless.)
