I've been thinking about setting up one to concentrate on slowing and dps instead of a lot of main healing, and then another one that concentrates heavily on debuffs/slows and main healing. That way I can call the specific .ini depending on my group makeup and what I want to do. There are times where my shammy is grouped with my cleric, who never has an issue healing the tank in group content, so I'd rather have the shaman slowing and dps'ing.
