There's really only two viable routes right now.
Assassins + anything. Gunslingers + anything.

For some reason I am really unlucky when playing assassins. I agree they are probably strongest comp. But everytime I play them I am losing half of the matches because my assassins cannot jump behind carries because enemy frontline won't move or because they focus wrong units and get melted before they are able to get that 1500 dmg crit. Also I don't see how can assassins win vs Glacials.
Anyway I think all routes are viable because you cannot realibly get the items you need for comp you are given and neither you can reliably get those units the comp depends on on tier3/tier2.
yeah, pretty annoying. gunslingers doing AOE shrinks/red buffs/disarms/silences, and assassins jumpin in and instagibbing half your team in the initial 3 seconds .....
I'd like to add glacials for honorable consideration for a miserable comp to play against.

Thats a Riot classic. Here's our game: it has 140+ champs, now pick from the 20viable ones to actually win a game.
This time its just: look at all the synergies, endless possibilites, now take that gunslinger, voli or assasin(and no other comb) to actually have a chance to win.
"Every game is different", nope they all feel the same right now.
Yeah, TFT's rng and forced meta has gotten old really quick. Riot got their money from LLs so it's all downhill from here.
I would add Voli + anything as well. But yep that's it. OH WAIT. AT LEAST THEY NERFED PIRATES THIS PATCH ECKS FUCKING DEE
i disagree. 3/3 SS(Gnar, Swain, Shyvana) 2/2 Dragon(Shyvana, Aurelion Sol) 2/2 Guardian(Braum, Leona)
With either Shyvana or Braum as the carry. Braum(Thornmail+Gunblade+X) Shyvana(Gunblade+Thornmail+X)
