[help] Disabling or Limiting Battleground's Join as Group

[blukkie]

I'd like to disable, or limit it to around 3-5 people, the join as group function of battlegrounds.

Now I've looked around in the code and I found that this is the function that handles the Join as Group button (correct me if I'm wrong):

 uint32 GetFreeSlotsForTeam(uint32 Team) const;

So if I'd disable this, or alter its return value, would it make join as group stop functioning or would it also affect solo joining?

Or would I have to alter:

void BattleGroundQueue::Update(BattleGroundTypeId bgTypeId, BattleGroundBracketId bracket_id, uint8 arenatype, bool isRated, uint32 arenaRating)

Thanks in advance!
