With the removal of guild leveling in WoD, i think some customization can be done.
What about a talents panel for guilds? Like current class talents but for guilds.
Maybe the old talent panel (with point by point increases) fits better that the current:
- Tier 1: Fast Track (1,2,3,4,5) - Mount Up (1,2,3,4,5) - Honorable Mention (1,2,3,4,5)
- Tier 2: Blizzard Idea A (1,2,3) - Blizzard Idea B (1,2,3) - Blizzard Idea C (1,2,3)
- Tier 3: Mass Resurrection - Mass Summon
With this, guilds will have flavors that players con choose.
Obviously, the guild master can change those talents (with the consensus of their member of course).
