Thresh makes LC$ bigplays with long ranged engage and lockdown, is allowed to stay the strongest and most dominant support in the game with almost 0 counterplay.
Janna prevents LC$ bigplays with powerfull disengage, nerfedto the ground the second she becomes popular.

Edit -
Thresh nerfs V4.13:
Dark Passage Now only shields the first ally to be near the Lantern in addition to Thresh.
Flay Fixed a tooltip bug that listed Flay's slow duration as 1.5 seconds instead of 1 second.
The Box No longer deals additional damage to opponents that break extra walls beyond the first.
V4.4:
Damnation Soul lifespan reduced to 8 seconds from 14.
V4.2:
Attack range reduced to 450 from 475.
V4.1: The Box Arm time increased to 0.75 seconds from 0.5 seconds.
V3.12:
Death Sentence Cooldown increased to 20 / 18 / 16 / 14 / 12 seconds from 18 / 16.5 / 15 / 13.5 / 12. Cooldown now reduced by 3 seconds if Death Sentence strikes an enemy.
Flay Passive basic attack "wind up" damage now only grows when Thresh's basic attack cooldown completes
V3.10:

I feel like sometimes, a link says more than a thousand words.
xLyo1 votesjanna is op. one day won like 4 games in a row with her cuz those knock ups and ult are just amazing. also movement speed for all teammates that are around. she is great support. i agree with tresh, some small changes would be nice.
