[Other] Cataclysm scaling is way too messed up

[FizCap]

• [Location, Faction, Race]Uldum, Night elf, alliance
• [Name, Type] Cataclysm scaling, expansion
• [Problem Description] Almost every raid, dungeon and zone have messed up cata scaling, like the dragon soul raid the trash mobs even one shot geared up level 90s, almost every dungeon is impossible even with level 85s and a lot of zones do like 1/4th damage from trash mobs, it was so bad me and my friends had to skip this entire expansion it was barely playable
• [How it should work] Scaling needs to be fixed
