I'm a lonely Amumu

I'm decently new to the LoL community and I'm sick of playing AI games. I want a good team (not that i'm 'good') to play PvP with or just someone else to play anything with. My mains are Ekko, Annie, Ahri, Syndra and sometimes Ashe. I still need practice playing haha but the game still sort of confuses me.

Like, who should I buy next? And how do I build certain characters and all that jazz.

Add me if anyone wants, I'm level 18; arcanetonyy
