Shroud of Saints mana regen should not be static

[Pharazon]

Good insight, but missing the point. The discussion isn't what is the use for shroud, is that it's mechanic will make PIE worth less and less for WHMs.

If the argument is going to be made that Shroud should scale with PIE then you have to consider what Shrouds and to a lesser extent PIE's use actually are. The point I was making is that as your mana pool grows from adding PIE that you have more tolerance to heal less efficiently and need shroud less and less. At lower levels of gear shroud is your cushion for healing less efficiently and as you continue to gear up you have the built in regen making shroud less needed. If both scaled with PIE then you would not have no need for mana management at all and would end up with nearly infinite mana pools.

Long term shroud might need an update but at current gear levels with the way passive regen works I don't see any issues.
