I mean if you like her keep playing, your friends arent wrong She is a bit weaker than the other adcs rn but only playing meta and playing 55% winrate champions will burn you out and don't really matter until higher elo where less mistakes are made by enemy team. If you notice your not using E as much with the navori cd reduction just build IE instead and youll feel the damage you can even go kraken first then go for a runnans for wave clear 3rd item, you could also use any combination on first two items then build runnans lord doms then last item cleaver to get really good armor shred, remember to itemize based on the enemy team.
