Vocal Session (Items, Runes, Champion Pool, OP.GG Review)
League of Legends
This is the most basic way I can help you improve, by optimizing your champion pool, and rune/choices. In addition to this, if you want to ask anything about how to play x matchup, or what to pick into x champion as counter, I can answer all that during this session. Cheap, fast, instant effects, great for short-term improvement.
