So I was checking my quests, when an shaman wanted to duel me. So I accepted the match. The first thing he does is get on his flying mount and flew up on a tower and starts to shoot me from a range I can’t reach because I cannot fly in combat.
Though the whole match, he ran and flew out of reach to potshot me.
That is a very disgusting tactic and they should disable riding mounts while Dueling another player.
