I am planning to build an archer for my next D&D character for Adventurers League. I will be going three levels in fighter to pick up the Battle Master Archetype and from there I am considering multiclassing as a ranger. I have been away from D&D for the better part of 2 years and am unfamiliar with the ruling regarding the revised ranger from Unearthed Arcana in league play. My question is thus: can I use the revised ranger in Adventurers League and if not, is their any point in going ranger otherwise? I remember that the ranger was really underpowered and I know Unearthed Arcana addressed this issue. Also just to note, I am not planning on going beast master.
