TL v WBG League of Legends

I do not understand this game. Never played it so I don't really get how this works
TL takes one of WBG out immediately making it a 4v5
Yet WBG still takes down 2 whilst TL is unable to take another one out

Not all champs are as important. I don't know what play you're talking about but losing your support is not the same as losing your adc and also you can get out played. Is not like losing a 4vs5 in Valorant but kinda

Maybe they invested all of their ults and shit to kill 1 and then were left 5v4 but with everything on cooldown

TL is a choking hazard

to put it in valorant terms it's like if in a 5v5 site execute the attacking team kills the enemy raze, but then the defending team combo's breach ult & omen blind to push into the committing attackers & kills two of the players that couldn't run out of it. champions have different values in those kinds of situations and your utility matters in how much you can convert those plays
