Player interaction whether working together or against each other is one of the best aspects of gaming. I think Guild Membership could be incentivized for single players and guilds too. Players could be refunded X amount of their monthly subscription fee if they've belonged to one specific guild during the previous month. Guilds that have X player membership threshold could refund X more of the subscription fee to each member.
Secondly, guilds that have X combined member player hours could have an opportunity to obtain vanity items that do not effect combat or production (just skins, flags etc). These are just possible ideas warts and all, and I wanted to throw it out there.
