If the opposing side has more tanks than your team, they are more likely to win

Team with more tanks usually has a team with more focus on Teamwork.
Teamwork OP

This is how the game has been ever since season 4.

maybe stop playing 3 assassin teamcomps who keep stacking lethality.

its become a rare sight, that a team isnt running 4 squishy carries and a "support".

obviously those teams get crushed by armor stacking tanks like around midgame. so no surprise here.

ive seen the replay of the LCS game recently, and they were up against 4 champions who were stacking lethality. so naturally they reacted by picking 5 on their team.

riots reaction: nerf tabi.

like what the shit? how about doing something about the teamcomps that necessitate tabi being built so much?

lol my like my team can't be bothered to pick a tank at all

You go mid and it's like: "ok guys, I'm gonna go Orianna to provide a ton of utility. What you got?" "Uh, Riven top, Tryndamere jungle, Varus ADC, and Braum sup." "Oh... Braum it's all up to you."

This is how the meta is shifting.

Not necessarily. If they have all tanks, they deal a lot less damage. I'd say one tank and one fighter is the optimal tankiness for a standard team comp.

nope

its whoever has the worst feeder.

gone are the days a team could carry them

This is how its been since the beginning of LoL

for soloQ sure, as it´s easier to execute teamfighting with a tank opposed to full dmg comps when there is no coordination and the tank just marks a very clear target. And even then 1 tank with hard lock down usually is enough, a second can be nice to have...but more than that and you are most likly at a disadvantage.

Not always, too much tanks is just as bad as having no tanks, especially if the other team has tank shred champs like vayne, garen, etc. I'd say a balance of 2-3 tanks and rest carries/aoe nukers would be the best teamcomp.
