Instead of those systems I think they should make FFXIV easier to play.
For example, the DRG rotation is very long and losing their buff hurts their damage significantly. It could be made shorter. BLM is similar with Enochian. Could make it so you can cast Blizz IV even without Enochian. All DPS now have too many buttons, many does the same thing as another, for example, Painflare and Enkindle, Spur and Rouse, Impulse Drive and True Thrust, etc. I've been playing since 2.0 and even I get confused sometimes, there's so many CDs and buff/debuff timers to keep track of.
Once it's easier to play they could slightly increase the difficulty curve, I think that nerfing leveling/level 50 content was a mistake. They were good to teach you the basic skills of playing a MMO like paying attention to what the boss is doing or your debuffs.
The game expects you to play perfectly at 60 during certain content, while doing very little to train you before you get there. I imagine this is very frustrating to new comers.
