Guild Raid Bosses are something needed for guilds only to enlighten players to be in a guild basically for true guild content. If there is guild content it is being treated like a redhead stepchild because not that many players are up to the task of doing trails, dungeons, and PVP without any Guild Quest involved.
Guild Raid Clan Bosses have 4 boss modes, easy boss 1, normal boss 2, hard boss 3, survivor boss 4 with their rewards.
Guild Raid Clan Bossed leaderboard(x5) should be a thing as well. This is one of the perks that truly makes Guilds grow.
This is one of my biggest problems why being in a guild if there is no Guild Content No Guild PVP, No Guild Quests, No Guild Lessons(x6) on crafting Lesson 1 craft 150 of (?), Lesson 2 craft 300 of (?), Lesson 3 craft 500 of (?), Lesson 4 craft 1000 of (?), Lesson 5 craft 1500 of (?), Lesson 6 craft 3000 of (?) and so on. What makes you want to stay in a guild to keep it established?
