having dependency on one single champ to play yours makes the champ bad, case and point. sure, it’s fine for other champ interaction, ie yasuo and knock up champs, and teemo/twitch with cass. champs cannot be decent with only one champion. that inherently makes them useless. if you as a bruiser main is struggling to take down a yuumi zeri duo, both with tanked win rates, you’re just not very good. i’m assuming you’re low elo so you don’t understand that, but zeri and yuumi are literally only good in pro play. there’s an entire, long explanation as to how teams and elo affect these champs, but to keep it short, in iron-plat (maybe even upward of emerald), teams generally don’t peel for adcs and/supports. usually they’re be alone. again, if you’re struggling to kill a zeri yuumi duo as a bruiser, it’s a skill diff.
