Yoshi P said in a video that FFXIV wouldn't exist were it not for WoW. The game was a major inspirational source for this game. My question really is: Is the dev team willing to learn from the mistakes Blizzard made?

Blizzard literally went on a raging simplification spree. Notably pruning and removing tons of abilities from each class and specializations in the name of "accessibility". Shortly after the game went downhill big time. Skill expression is today completely gone in WoW. Every class plays braindead 1-2-3 button smashing that literally dulls your brain as you play.

I truly do not understand why the developers want to do the same thing to FFXIV. Heck, Blizzard even recently stated that pruning was a mistake. They're now trying to "undo" the damage, but that's likely going to take multiple expansions of work. Why on earth would you want to repeat this same mistake in FFXIV?

Having easy jobs is perfectly fine, but there needs to be jobs that offer also medium difficulty and high difficulty. Pruning and dumbing down existing jobs is not in any way acceptable, and is an insult to players who main those jobs. If you want to make something simple, then you need to create new jobs that are simple from the beginning - period. People are invested in their jobs and you're actively disrespecting their affection by making changes none of them asked for.

By all means, continue to remove abilities and make the game play itself. You will not gain more subs; but you will lose half your player base from your arrogance.
