Introducing VistaWoW Drop Boost

VistaWoW Drop Boost will increase the number of items dropped from dungeon creatures based on the participants GearScores.

All 5-men Normal dungeon's creatures will drop 1 more item if 2 players have GearScore less or equal to 3000.
All 5-men Heroic dungeon's creatures will drop 1 more item if 2 players have GearScore less or equal to 3500.
All 10-men Normal dungeon's creatures will drop 1 more item if 2 players have GearScore less or equal to 4000.
All 25-men Normal dungeon's creatures will drop 2 more item if 5 players have GearScore less or equal to 4500.
All 10-men Heroic dungeon's creatures will drop 1 more item if 2 players have GearScore less or equal to 5000.
All 25-men Heroic dungeon's creatures will drop 2 more item if 5 players have GearScore less or equal to 5000.

There are mechanics to prevent cheating:
- You must be wearing at last an item level 158 of Uncommon quality. If your item is inferior, it will be considered as an item level 158 of Uncommon quality;
- Same goes for empty slots;
- Only the highest GearScore detected during the session will be taken in consideration.
