Chaotic is a beefed up Extreme with cheesable bodychecks and a DPS check that is nonexistent even when you're absolutely braindead. FTB requires sincere organisation and the will to actually pull your weight, but is - aside from boss 2 as well as boss 4 daggers - also just a beefed up Extreme. And Extremes are very much casual content because of how free they are (we don't talk about 4head breaking PF).

In case you're literally an NPC who only does normal content, you still get way more than midcore to hardcore players:

- 1 dungeon per patch
- TT
- farmable series rewards you can literally grab from sandbagging in Frontline
- 4 normal raids every second patch
- alliance raids every second patch
- base OC because you can farm a fuckton of glam plus a mount
- MSQ is inherently casual content
- treasure hunt
- cosmic exploration
- continuous gold saucer rewards
- ocean fishing exists
- housing is casual content. as a housing main i do get to say this

Like seriously, the only actual hardcore content in this game is Ultimate and some particularly nasty Savages. Savage is midcore, and again, all Savages become trivial in two patches' time. Casuals have enough. FTB isn't even hardcore unless you consider not being an antisocial leech hardcore.
