Hey there!

I'm new to FFXIV, and I was wondering if someone could use a quick guide for the differences between DPS. It's pretty obvious the type of damage they do (as far as ranged/melee/dots/dd/etc.) I just can't find specifics about end-game roles like buffing/debuffing/crowd control.

For example:
Which classes bring buffs (and are these buffs highly desired?)

Which classes bring debuffs and how desirable are they?

Which classes are crowd-control oriented?

Thanks for the help!
