You should focus on your TOP 5 heroes for Arena. Two infantry hero, Two Lancer, 1 Marksmen or 2 Marksmen as per your hero. Upgrade those hero and apply mythic gears to them. As I told in video play arena before 10-15min before server time reset. Hero position is important in arena so always check your before opponent hero before starting match.
Ótimo vídeo. Gostaria de saber como devo subir o nível deles. Se preciso ir subindo igualmente ou se tem que priorizar algum equipamento os classe de herói?
