I have issues with the vast majority of your post but I want to single this Resurrection change, as one of the worst things you can possibly do to the health of the game, why, because this change will only affect prog and lower skilled players, Resurrection is only useful if someone dies else it is worthless, look at Dps side of forums for arguments on the value of Rdm's/Smn's raises, how it drops off the moment no deaths happen and shouldn't be factored in at all.
Current Raise allows recovery in things like 24 mans and dungeons, your raise would not, and if you think the majority would not be in an uproar the moment they no longer can face roll across their keyboard to win XD XD XD.
Your raise would just arbitrarily extend progression on fights and not even all fights mind you E8s has a fair few moments of you wipe if not all 8 alive let alone enrages.
Next what would you do to tax healer mp economy the only thing that can dent Whm, Diurnal Ast and Sch mp is Raise, Nocturnal Ast has shields + raise so your version allows healers to completely not care about mp that is trading something you perceive as promoting bad play for making a redundant stat something far worse because it will affect more skills.
On that note promote bad play?!!! XD XD XD how? because someone can raise them with an 8s cast time? do bear in mind ShB speed up a lot of aoes and 8s of standing still does not happen as often as ARR/HW did, because a healer might decide that dps who died 5 times is not worth their 2.4k mp while rest of party needs attention? What bad play does raise promote by being an 8s cast time?
People won't do mechanics? well i've got news for you they wouldn't do them anyway regardless of what raise is like, raise as is let's the healer move, why do you want to punish the healers? aren't we punished enough with our downtime being 1 goddamn nuke and 1 god forsaken DoT.
Everything you listed for it can be solved with 1 thing Communication, random people Raise/Swiftcast macros, organised group chat/discuss your organised so do some organisation on who has raise priorites.
