Alright, so I decided I would try to raise an airship all on my own and this is as far as I have gotten by myself. Currently have 2 lvl 2 airships along with 2 parts on one airship... If any guilds are interested in joining forces with this one, I'm all ears.
Uh just curious, what do you mean by merge? Do you mean giving up your effort you put into after getting the airships and moving everyone in your guild to another guild, or asking another guild to come into yours?
In our case we already invested a lot of our money into other things like parts, so there's no way we would want to disband our guild to join another's... I'm pretty sure for any reasonable guild size out there, they already have invested their money into things like parts and airships as well. I believe you may be better off trying to recruit new members if you want to keep your guild (ie, airships) rather than asking other guilds to disband and join yours, basically.
The easier thing to do is to just join a new guild, but if you're attached to the investments you made already, I would suggest you just continue running your guild as the leader and instead try to populate it with more members.
