I think we'll have to agree to disagree the initial point then (which is totally fine!), but I'm not convinced playing a goblinoid would automatically lock you out of Grove content, just adds the challenges that naturally come with playing a monstrous race.
Either way, I imagine they have a list of other races to add long before goblinoids
Well, how would you allow a player goblin to enter the grove? Disguise Self can work but the character would have to make a check with every npc they encounter, every day.
I'm curious if you have a solution. If you do, it doesn't hurt to let Larian know.
