The more I think about it, the more it is obvious that some sort of epic shield fighting feat is or should be under development.
The questions are:
"What should it bonus and what type of bonus?"
"AC?"
"Shield AC?"
"PPR?"
"MMR?"
some combination of the above?
Also, we do need Metamagic Feats to scale somehow in Epic and the current Epic fighting feat toggle format lends itself fairly well.
Main questions in my mind is the math and application.
How much bonus universal spellpower will be needed to bring caster to a level where it is comfortable close to other forms of combat?
We will probably see Consecration as the new cocoon. Cocoon gets wipe out pretty quick for anything on the front lines.
Likely the whole charmed situation will be changed to:
"Charmed mobs take the same damage reduction as Allies."
Which leaves the question if Suggested Mobs take the same route.
If we are balancing power groups, then it would be nice to adjust the whole damage scaling in Reaper or at least consider thus.
Currently:
Melee damage is reduced the least by reaper reduction
Ranged damage is reduced more
Caster damage is reduced the most
I realize the whole running away from mobs is factored into thus, but it is not exactly fair and definitely should be examined.
My opinion is that the whole perching thing is a factor in this and technically perching is against the rules of conduct, although Devs keep designing boss fights with places to perch thereby encouraging players to create ranged toons and perch thus thereby defeating the whole "we want to help melee dialog".
