Well as you said, its like A1S and A2S is for midcore, A3S and A4S for hardcore right. On first hand i started as casual raider (2-3days) and took few weeks to down A1S-A2S, and then became midcore (4-5days) and cleared A3S-A4S within 2 months. I think they just did not fail on A3S and A4S beacuse they are still "fun" but the problem is that the community is mostly between casual and midcore and only few can commit the time required to clear the 2 last floors, thats the issue. They made 2 raids for "middle ground" as you said, 2 raids for "hardcore scene", so now they going to give Savage Midas, open for most population = midcore, focusing on mechanics instead of dps checks just like old coils. Plus they gonna Nerf Savage Gordias, then more ppl will be able to got his A4S mount. So the issue is solved, right.
