Guild Splitting
Judging by the tools they’ve lacked in the past I’d say guild splitting is very far down the list. I think it’s safe to assume that won’t happen.
It’s a terrible situation :/ Don’t expect any help from ANet, I’m afraid you’ll have to sort this one out yourselves.
In any way, is it that bad? How many are you? You still share the in game chat, so you can still have some fun together.
