I think that would make it a lot harder who on the newer healers who just started learning their class but rushed to 60 because " I WANNS TO heal SAVAGe with my Secondary class"
(Next part is just coming from what I heard, not experience)

And in response to what you are saying OP, A4S if you do not cheese Royal Pentacle or The Straff dolls is an extremely difficult fight for healers requiring a huge healing requirement. I think if you wanted to and were good enough, you could do A4S as it was intended and find out that Healing Output in Savage (at least for A4S at current gear levels) is what the raid was built around. That's why a lot of people still can't clear A4S. (Could be other reasons as to why though of course)

That's the difference between Coil Raids and Savage Raids which started from Savage SCOB is that the healing requirement is truly insane due to high incoming damage to party plus mechanics. I like the idea of Savage Raids but I think it should have been done like SCOB was and not make Normal fricking CT difficult but instead make it Raid difficulty with Savage being near impossible unless you're a really good group.

Some teams like the difficulty of Alexander though and their qualm is more with how specific battles played out. Creating a better raid storyline and more interestmadebattles go a long way into making a raid tier successful.

Biggest issue in my mind for first set of Alexander raids (Call this Binding Coil of Alexander) was that they made A4S so difficult that even extremely skilled groups are just getting clears. Because it has the name Savage attached to it and can't have echo or gear lockout removed from it yet. They catered to the World First tier of raiders and didn't think "Hmm, what would the other 99.99% who arent playing for world first think? Would they find this fun or too difficult? Fun or too tedious? A lot of people got it right when they said A3S should have been the final raid in this tier. Having the most fun raid in the middle is poor raid design.

In fact, people might be pissed if this Savage got echo at this point because it is "Savage."

Sorry for such a long post. These are my views.
