WHM question

1. The enmity generated by WHM heals feels pretty high and is sometimes very difficult for the tank/s to deal with. Having to slack with healing to mitigate this doesn't feel fun and neither does not using the full WHM tool set, it's probably not much fun for the tank either. Are there any plans to adjust WHM enmity?

2. The small delay between using an instant 'off the global cooldown' spell and using the next spell feels clunky and can cause mistakes to be made. This is often an issue when using a panic spell such as swiftcast. There is also a delay when casting benediction, I feel that this needs to be instant. Are there any plans to reduce or remove this delay?
