It's not that I don't think it would have the desired effect on casual content, I just don't think it would have much if any effect at all. On higher end content it should streamline things, but I don't think it's going to be an improvement, rather it just addresses the bloat. Personally I think that recent 24 man content is the absolute low of the game for healers, perhaps even more so than soloing. Aglaia is unbearable on WHM for me at this point and Euphrosyne is only marginally better.
