Because someone has to keep the RDMs in check, and some body has to wade through all the BS and whining to know what is going on in other classes. And tbh, I laugh when RDMs talk about how other classes are complaining, but RDMs are the worst, and have been for YEARS, I would even argue since the dawn of FFXI lol. Contrary to what others think, I do honestly believe that the opinions shared on this forum matter, and that they do read and listen to what we say or discuss. And if such idiocy is mainstreamed and eventually becomes a fact of the game, I can only blame myself and others that didn't bother to step in and place the boot of reason on the ass of a RDM's idea. I do not shun all ideas, and I usually add what should be the focus, and if I do agree with an idea, I will either accept it outright or say means in which it should be adjusted.
And honestly, it doesn't take a level 90 RDM to figure out what the job does, thats like saying the complexity that is WHM.... What a joke, I mean sure you should regulate your hate and such with cures, yet any PLD can understand that since they are on the opposite side of the spectrum. Simple understandings of the mechanics/spells/tools give you a very clear understanding of the job. It really doesn't take a genius to play RDM, it just takes good distribution of buffs, and a good eye on timers, as well as health bars, and decent debuff gear, INT gear, and MND gear to play the job. If a 90 is what warrants a discuss on such a simplistic job, hell give me a weekend and I'll have the job, which is basically deemed worthless in terms of having SCH or WHM leveled, high enough so that I can still post my exact opinions in such threads.
If you want complexities, play PUP or BLU, now that takes some know how, when it comes to RDM, I refresh, I haste, I cure, I regen if possible, I paralyze (II), I slow, and I blind if possible (oh and maybe pop of a nuke or two just to feel like I'm contributing other then sitting there with my thumb up my arse). I basically just nutshelled the role of a RDM, at least in Abyssea. And for those that say "Well thats Abyssea!", of course, because thats the only content that people are playing, and until that becomes obsolete, there is no point in discussing other content that I can practically solo on my 90 BLU or low man.
