Well maybe dwarves just don't lend themselves to being rogues, just like Halflings have a tough time Intimitanking the Epic DQ. Shucks gee golly, roll something else. Rogues get just as many feats as Paladins, yet a fair share of Deeps Pallies manage to find an extra feat slot for an exotic weapon.
Either Rogue 20 is strong enough all by its lonesome, or its not. If you like it, stay pure class. If you don't like it, multi, get the feat, or better yet - ask for the things rogues already have, like the capstones and PrEs, to be improved.
Don't ask for a second-tier melee (based on BAB, not Deeps) to get an Exotic Weapon because all other rogues get 3 of 23 Martial Weapons. And yes, I know its Martial. To full BAB progression Dwarves.
October 12th to November 5th without getting a single response, in the Suggestions forum no less? Its casting Raise Thread as a 9th level Poster.
Warchanter 2 gets it because theirs is a martial PrE. Not that it particularly matters, since most Warchanters I see already have two levels of Paladin, Fighter, or Barbarian.
"He's an assassin, so he should use an exotic, non-light weapon." <- Did I quote that correctly? The two Martial weapons that rogues get (melee) are Short Sword and Rapier. Both Light weapons. Light = Rogue.
Its like getting sneak attack damage with a ballista. Its a joke. If anything, the PrE could get an increased crit multiplier while using light weapons. Rapiers would be sexy for any race if they were x3 Crit.
Edit: Also, this thread was mainly about a Cleric. Rogues, or a specific PrE, getting Dwarven Axes should probably get branched off to another thread.
