Thresh is a very good support to climb ELO with. He has a lot of utility with the ability to get picks and is able to disengage. His Q - Death Sentence is a very good tool to use in saving teammates, or getting picks. His W - Dark Passage is very good for saving teammates or shielding someone. Your E - Flay is a good spell for disengage or flaying someone into your R - The Box wall.

Thresh is a very good and highly contested pick for Ranked. He offers a lot of what a support needs, and offers a carry role as support. Thresh is definitely a support champion that can carry at any ELO.

Thresh is a very good team-oriented champion. He allows the team to siege waves by having the pressure of his hook being able to catch someone out very easily. His R - The Box can lock in members of the enemy team and keep them off of your back line so they can deal as much damage as possible. His E - Flay can change a fight by flaying someone out of a dash, or by securing a kill by flaying them into a skillshot. His W - Dark Passage can save a teammate in a sticky situation. His lantern follows thresh where he goes until the person who clicked the lantern is at Thresh, so flashing walls works while your ally is traveling to you!

Thresh is a great champion to learn, even if you don't play support. If you can play this champ when you have to support, you can easily carry a game from a role that doesn't seem to carry.

I stream games often on my Twitch as well.

Also, I learned a lot about how to play Thresh from PAlNLESS. He is a challenger support player that streams here.
