Yes, many jobs can farm or solo exp faster than a rdm can, but only a rdm can solo HNM's or gods. You're completely ignoring this fact and aren't giving a single justifiable reason for a rdm melee buff. Saying that soloing EP-EM is the same as soloing a level 80+ mob is beyond stupid. The only reason you want a melee buff is so you can either
a) solo more shit, which you don't need since you are the only job that can solo most things in the game already, or
b) melee in exp parties.
So you get savage blade but not vorpal, so you get some of the best swords in the game; so what? As a whm, I get the best clubs in the game, along with the best club weapon skill, but I'm still not whining about wanting more stuff to solo with. RDM doesn't need a buff so they can solo every HNM in the game. Unless there is a fucking huge buff or they completely gimp themselves as a mage to increase their melee damage to a "meh" level, a rdm melee buff would be a complete waste of time.
