[BUG] Lady Vashj's Tainted Core still roots players in place

[Kolmarwow]

1. Current Behavior

1.1. Description

In Serpentshrine Cavern, the final boss Lady Vashj has a mechanic in phase 2 where you need to pick up Tainted Cores from Tainted Elementals to disable her shield generators. In TBC these cores rooted players in place when you looted them, the idea being that you throw it to another raid member standing by a generator. This mechanic was removed in original Cataclysm as seen in old patch notes & videos but still exists in Cataclysm Classic.

2. Expected Behavior

2.1. Description

The root from Tainted Cores should be removed as it was in original Cataclysm.
