My cynicism hangs largely on the lack of change RDM has received. Sure, the level cap increase happened, we got some "mandatory" tier ups in nukes, but not really much else. WHM got Addle and our Gains in AoE form. Our melee game improved some in both WS choice and gear, but it's still never desired. Enfeebles not Stun are still generally useless, too, and Immunobreak didn't really address RDM's fundamental enfeebling issues at all: It just made it easier for other classes to hit the same walls we do. We did get Shield Mastery, though!
And while other classes may not have changed as much, it's more of a testament to how good they were to begin with once you shed RDM's veneer of Refresh/Convert Immortality. MNKs were good DDs at 75. Now they have even better gear and a couple JAs on top to help them along. More comparative to RDM, BLU grew exponentially. Not only did they get new (good) spells and gear, they got new traits on top like the ability to set DW3 so they can also /WAR for Berserk (and in the future, /DRK). BLU could also see some interesting tanking potential if the Defense tweaks Matsui hinted at amount to much, but the enmity system is still an elephant there.
So, despite RDM's gains, it's also "lost" things to the times. Solos don't mean much or done more comfortably by other jobs. Pink magery, much as I don't miss it, is basically the last resort after WHM and SCH healers. Refresh isn't as needed due to gear and stronger MP efficiency options of other jobs like Arts or WHM's Emp legs. Slow/Para means nothing on mobs whose auto-attacks are technically TP moves. We also have no unique procs, or at least when we did, they were locked behind merits, forcing RDMs to gimp their decent spells just to have them. Personally, I won't be sad if the proc system never returns in future content.
So, while SE could try to take SR's approach to hybrid-friendly content, my fear is such content wouldn't be rewarding. Look at Campaign, at best you got the Rose Strap and then some level 68 sets. A solo friendly activity, sure, but I also don't believe a RDM has to play solo to actually BE a RDM, and not the imitation WHM or BLM some look to it as, or the WAR it never was. The job needs help, all around help. And as much as I hate to say this was the inevitable fate I saw way back in 2004 once our toys became tertiary, well, here it is. And some people are happy about that.
