These suggestions read like a WoW game with some single player RPG stat mechanics. Basically, you're asking for more damage to be output by a boss in order to force healers and tanks to take on additional responsibilities while dps keep as they are. This would potentially create a high skill divide that can no longer exist in savage and below modes with FFXIV's population as it is now. If you're keen to notice people complaining about their roles, you should be keen to notice people complaining about how hard savage is.
