@o_scheeckHi. Quick question: do you guys feel Beast Master Ranger is fine/balanced as is, compared to other classes? It’s hard to compare a subclass to others without knowing the context: social interaction, exploration, or combat.

Sage Advice: Master Jeremy is right, it depends on context and your DM campaign.
If your adventure is in a multi level mega dungeon could be an hard task for Rangers, Druids and, if dungeon is very narrow, casters that can’t use their area effects/long distance spells.
But the problem could be similar in a city, where is more important to be sneaky or charismatic : area effect caster or Barbarians could be very cumbersome.
So my advice is to talk with your DM before campaign start and decide together wich classes could be better for all of you.
Our home rule for Ranger beast master is , beast can act on its own turns and initiative, and receives new commands as a bonus action from the ranger. The beast is augmented 4x ranger level in hp.
