Looks like we're possibly going to get a dedicated debuffer (which won't be their only actions, it sounds like some people honestly never touched a FF game before lol.)

After 2.0 it may go to whatever job/class already exists, but I won't be surprised if we DO end up getting a new class, I mean in FFXI there was nothing wrong with a RDM or BLU's using Debuffs or COR's enhancing debuffs so I don't really see a problem if they introduce a new class.

i dont know what kind of "bettering" this should be
The kind this game needs? So they can actually keep balancing it? Why do you think MMOs are usually balanced and FFXIV wasn't? It wasn't because it was unfinished, XIV gave you too much freedom, now they're fixing that and rebalancing everything a step at a time.
