Astrologian Job Idea

[HeroSamson]

We will probably never get different types of jobs that are different than what its setup for which is only dungeon.

Tank > healer > DPS > (support though its mixed with DPS)

FFXI it worked cause most of the stuff happened outside of the dungeons and game was made revolving around a plan of attack due to if you failed you lose pop item.

Here I don't see anything that needs other jobs you could probably beat the game with the setup we have now.

Would just be better if they did a more evolved versions of the jobs themselves and re-level for different skills

Got ninja to 50 basically rogue with Ninjutsu so basically why make new jobs just paladin > dark knight new skills > whatever tank is next

By that logic, they didn't need to add Rogue/Ninja or plan to add Dark Knight and the other hinted at classes/jobs in Heavensward either (minus fanservice) because most people already beat the game with the original, 2.0 jobs.
Its just adding another way to play the game and grind, for variety and replayability's sake.
