In short, I suggest replace the 30,000 influence Guild Bounty unlock with 3 unlocks:
Guild Bounty 1, 5,000 Influence and Art of War 3
Guild Bounty 2, 10,000 Influence and Art of War 4
Guild Bounty 3, 15,000 Influence and Art of War 5
I think this is appropriate because smaller guilds that can afford these new prices for guild bounty tier 1 or 2 can probably handle those tiers. This would make this great new content available to a much larger portion of the population. A similar approach could be taken with Guild Trek.
