Are you sure it's not that you're team comp was horrible, you and your top fed. Like they were going to win if there top was darius or someone else.
Like this shows you have no clue wtf to do vs mord "All he had to do was flash banish my arc, and heal his way to victory." Like you know the adc isn't everything right? You know the enemy is down a player also right? You know your neeko and it's basically impossible for a mord to kill you right? Especially with that build right? Like you know you didn't have %pen in a 40 min game right?
Like how about you try learn about how to fight a champion before complaining in fact I'm pretty sure that the fact he was mord give you a chance. Since if that was a darius or renekton that fed you would of lost Much faster.
Please don't say a champion is op when he is fed since it means nothing.
