Yea man it could be worse like a lot of crybabies (those who gives first blood then afk just because their prepick champ got banned by the enemy team, which is no one's fault). And definitely I love to play such a hard hitter champ as Yi, hit harder against adc (as long as in attack range) or one that like Vi (Kha'Zix too but he's kinda dead at grouped war).

Well patience in action, just wait them to use their CCs/ultimates then you good to go. Though I'd say that's rarely the case, because diamond tier is pretty much same as emerald tier I mean both are zoo (too many animals lmao).
