For the record, my main job is ranger. I have both a relic and an empyrean weapon for the job, and as far as the capability of this job goes, its is a superb DD but it has not, since back in 2004/5, been the supreme damage dealer in FFXI.
I also have an Ukonvasara warrior, which is not my main but rather a secondary job and is therefore not anywhere near as well geared or set up as my ranger is.
I say this now, because I am a little disappointed in the events following the last version update. The introduction of the new merited weapon skills was fantastic - I enjoy Last Stand and the dagger weapon skill a good deal. They are beefy weaponskills that do very consistent and decent damage outside the abyssean front, and are great for voidwatch in its old andn ew installments.
HOWEVER...
The subject is Tachi: shoha. In my opinion, the weaponskill is overpowered to a very, very large degree. Samurai has been in the past one of the best stock damage dealers, and abyssea made them fade from the endgame scene for quite a while but, sweet Jesus, what a revival! A two hit Weaponskill with a strong fTP modifier and a 100% strength modifier when fully merited is fantastic. But, alas, it is also obscene.
Speaking for a base of players that had to sweat, grind, and work very hard to achieve the pinnacle of my respective job, it is disheartening to see players pick up the job samurai, merit this weaponskill three or four times and grab a subpar weapon off the AH and consistently do higher spike damage, more frequently, than I can. We're not talking about a difference of a few key pieces of gear; A Samurai can grab a cheap or easily obtained weapon and thow on a little bit of gear and do ridiculously well, where in the same situation any other job would fail horribly.
It is not the job, though, it is the weaponskill. Samurai was quite capable of holding its own with Tachi: Fudo or Tachi: Kaiten, but now any samurai fresh out of windurst woods can do as well or better than their predecessors with a minimum amount of effort.
The end result? A gradual shift to SAM-o-mania, as in the 75 cap era, albeit samurai is considerably more powerful now through its new weaponskill than it was in relation to all other jobs at 75.
My opinion would be to modify its strength moderately, by no means reducing it to irrelevance, but bringing it back to being on par with other jobs. When a Samurai with a magian great katana and average equipment can easily out perform someone who took the effort to make, say, an Ukonvasara (PRE-NERF!!) and the gear out their job well, there is a problem. When a samurai's own empyrean weapon and weaponskill and its own relic and relic weaponskill are completely and utterly replaced by a great katana that can be created in the course of a week by someone working by themself and a weaponskill that requires a few solid hours in an abyssea experience alliance, there is a problem.
Tachi: Shoha is a great addition to the arsenal of the endgame linkshell, but it is too powerful to the point of redundency.
