Champion/Rogue weapon

  • For the longest time, ch/r has used 1h hammer and fastest dagger. It was good for maintaining rage to keep rune overload going indefinitely in long fights. Now, I see ch/r using 2h hammers instead with attack speeds of 4. I haven't done any endgame dungeons (or any dungeons in Arcadia for that matter) so is the 2h hammer that better weapon? Any comments from super uber ch/r will be much appreciated. And can 2h hammer be used in doing world bosses?
