Hi, this is what you must do to get 1,5k healed every 2 secs.
1. Get a druid, party and make him stand in front of an instance entrance.
2. Make the druid cast (Tranquillity)
Use rank 5 for best results.
Now make the druid cast tranquillity, enter the instance while druid is casting.
For instance if you want to get healing bug on your rogue, make a druid cast tranq while your rogue runs inside the instance...
