Inside abyssea and outside abyssea are 2 completely different games. Inside, EVERYONE is an epic DD if they can use a crit WS. Period.
Thf is only a tank in very low man situations that, if you dont like them, never have to do. Inside abyssea, thf can tank a lot of things, but when every DD has over 3k HP and MP for healers is limitless and everyone does obscene damage, ANY DD can tank.
If you are not a moron, THF dd is amazing.
You will have to define 'amazing' and then reduce that a few notches because not everyone has your mandau, or a twashtar. For joesmoe thf OUTSIDE abyssea, the damage simply wont be there.
Can thf be a respectable DD? Sure if you put a lot of effort into it to catch up to an AH level drg/war/drk etc. A good/great thf can beat on most people? Hell yeah. Can a top tier thf match a top tier war/drg/drk etc? @#%^ no.
But the thing about FFXI is, ANY job can stand out among the masses if you put the time into it. Some jobs just have an easier time doing it, but if you find someone with the same effort into a better DD oriented job, they will mop the floor with you.
Just as an example, i started pimping out my brd for battle a while back. Most recent (non-abyssea) parse had me at #3 out of an alliance. I beat everyone but a ukon war (by only a little bit) and beat a drg (but lost when you count the wyvern). I mopped the floor with sams, nins, and everyone else. on BARD. Now, had I been on thf i would have kicked even more ass and probably taken the parse. Had I been on my drg i would have curbstomped everyone.
You can be 'impressive' on thf compared to other players. But the problem with that is that most other players just suck. If you take the time to understand HOW dd works in a rather technical sense (or just follow the advice of those who do) you will be a god among men, but thats only because most of the playerbase is ignorant o how to really do damage. Not because thf is an 'amazing' DD.
TLDR: Knowledgable player DD>>>>>>Ignorant player DD. 'heavy' DD>'light' DD. Thf is a light DD(for lack of a better term. Its not a war/drg/drk). If you take the time to gear/understand DD, you will be better than the vast majority of the playerbase no matter what job you play. But that doesnt make thf 'amazing'. That makes you an informed person beating ignorant and/or lazy people. Edited, Aug 22nd 2011 3:56pm by Banalaty
