?? you're vastly oversimplifying shit. Yolo pick TB worked if:
- enemy team didn't have tools to reliably push hg (whihc is a problem with hg itself, and with heroes like DP, Pugna, Rastha being nerfed after TI4 or just bad)
- enemy team didn't have a carry that could do anything late game vs terrorblade
Comeback mechanic isn't punishing for the better team, it's rewarding teams which understand the game better. In this case, teams who don't draft early game strats with no reliable HG push or which don't draft even a single lategame core.
A simmetric game can't have a mechanic that favor the "bad" team it's just impossible.
Comeback made all phases of the game comparatevely equally important, whereas now it seems it's only the first 10 mins that matter. This is a game where advantages breed more advantages, and need serious mechanics to avoid the game just being decided by the first tower in 65+% of games like it was in 6.82.
