I'm only going to talk about ff14 here. Hate is easier to lock, you don't have to deal with mp management much (especially on dd mages) or elemental information for blm, things are simpler outside of having to constantly move because of their danger mechanics/activities during the fight (like wow). There's not much of a fine balancing act between support cure enmity, tank enmity building, and DD enmity. Because you don't have to slow down it may feel like a nonstop marathon and is more fun to do, but you worry about the additional things they put in the battles instead. The moving and having to be accurate is indeed more prone for failure but that's a bit of a false sense of difficulty to me. To me it just seem like added chaos because you don't need to worry about a lot of other stuff. After a while, and after the gear upgrades, it'll just be a dance, and become even more routine than anything. One too many mistakes from anyone can force a reset. Everyone wipe.
Btw I didn't say FFXIV wasn't challenging, just the open world stuff. You asked a question, I gave my honest answers. I don't need you to agree, I don't think i'm basking in nostalgia also. Especially with how easy the environment is.
The good thing about this new fighting system in FFXIV is the fight possibilities is probably unlimited for future battles. They won't have to add additional mobs to make the fights tougher, or hidden ways to stop the mob from spamming super abilities type stuff. Though they may still require and limit combatants. I'd rather they allow for going in with how little member count as you want, even solo for whatever reason (especially the times you know you can do it without that extra person but 4 or 8 is required).
