Hello again and welcome to my in depth thresh guide
I am wesley2kill and im currently a silver 3 support main, i main thresh and blitzcrank and on both champions i have 65k champion points
in this guide i will go over a couple of things
-how to play this beast
-build
-runes
-masteries
-pros/cons
-how to land hooks most efficient

Pros
-good cooldown on grab
-has safe-ing potential
-very good CC
-can carry games if played well
Cons
-Team Reliant (obviously)
-Ability Reliant
-not very tanky in early stages of the game
-no escapes (i think his ult is not an escape)

thresh is a team Reliant CC hooking tanky god and when you play him a lot and have mastered him you can carry games with ease

obviously it depends on the adc your playing with this is what i love about thresh thresh can play safe but he can also play aggresive which creates versitility which is in my oppinion one of the best things about thresh
if your adc wants to play aggresive what you need to do is hook in the adc (i will go a little more in depth how i tend to place my hooks later) have 2 drag animations then reactivating your Q and then E him towards your adc or throw a lantern to the incoming jungler to help him get by faster
if your adc wants to play safe try catching the poke for him/her and if they want to go ingage just E the adc away
in midgame you can also start to roam some other lanes and try to get them kills to because if u are already fed you obviously dont want to be the only one to rely on so why not feed other lanes :D
in lategame all you want to do is hook in all the carrys the enemys have your allied team will do the rest

what people tend to do on lower ELO when they try to hook is aim right for the enemy adc
in my oppinion this is not a very smart move unless they have nowhere else to go
because thresh his hook animation is quite long its easy to dodge but you cannot see where it is gonna go when he starts the animation
here is where you start playing mind games what you want to do is place the hook on where u anticipate the enemy adc is going to go so place the grab next to them
when they see you starting the animation they will move to the side to dodge it and voila right in to your hook
works every time xD

I hope you can learn something from this guide and if you have any suggestions on something i should add to this guide just leave them in the comments i will try and add them to the best of my ability
but above all keep threshing the enemy team
(lame *** joke):P
