Well, surely u can remove one Goblin from your Guild, if there is 30, probably there is a few that is a little inactive. OP is a dream for any guild, 75000 gold as well as 200 trophies a week is really good.
Would you like to join Light Army? I am not the leader and it is full atm, but I am very sure we can remove an inactive one from the guild. I can try to contact the leader. We are currently 11th. Let me know.
However I now have sent the leader of Light Army a request about if you could join us. Since we are 11th place, I am sure you would be gladly to join. But under the circumstances that you provided in your main post. Just make sure that you are in no guild, and it will probably go well.
