Guppy - Guild Upgrade Planner

The addon lets guild members who have it installed share their current gear, chosen spec, and role with each other through addon messages. Based on that shared data, it estimates which dungeons offer the best potential upgrades for each player.

It then uses those player-specific upgrade scores to recommend the most efficient 5-man dungeon groups and even suggest two separate 5-man splits for around 10 players online. In short, it helps a guild decide who should run which heroic dungeon together to maximize the chance of meaningful gear upgrades.
