You're not sharing "facts" you're clearly ranting.

This game is BARELY reworking or revamping stuff, not even close to what you're making it sound like.
It's one of the areas were Square actually does an amazing job compared to most other MMO devs.
Let's compare with the most popular other MMO. World of Warcraft. The Devs constantly creates new systems for every expansion and then deletes it while barely learning anything of what made it good/bad.
Square does NOT do that. They do small touch ups, Dragoon has pretty much been the same class since HW except that they've fixed some issues with it and they've added a few more abilities. There's very few examples of classes being "remade" so you have to RELEARN it. It has happened but Square very rarely goes there.

This thread is just a mess, especially since you started off with the whole "Square pls dont rework/revamp" stuff only to make it about lack of content? What?
If you want to discuss lack of content then start another thread for that.
