Lets find a way to satisfy small guilds and large guilds. Lets make progression. But lets not make grinding for influence a thing.
Suggestion: There will be two different tiers of Guild missions. “Tier 1” guild missions satisfy for small groups and/or small guilds. They are balanced around 5+ players and they can be bought by an officer. “Tier Epic” guild missions satisfy for Large guilds. These Guild missions requires a large guild and they are epic and memorable.
Tier 1 Guild missions are somewhat easy and plentiful. Smaller Guilds have more accessibility to these. It is to be expected to see many of these Guild missions everywhere. Breathing more life to all these empty zones. There will be a hundred of these all around the world, which are mostly bounty missions.
Tier epic guild missions are gated. Your guild have to complete successfully a certain amount of Tier 1 guild missions. For larger guilds, they are supposed to separate the Tier 1 guild missions task to multiple guild members so the guild can work their way up to the tier epic guild missions. Then, the entire guild can play the Tier epic Guild missions to get the best fun and rewards there is.
This way, smaller guilds are not gated and still can have fun together working for the tier epic guild missions. Larger guilds, on the otherhand, can get them faster. But the point is that no one is gated from doing the content.
