Personally I think Ranger -before- the extra slot items they have is more powerful, especially in a PvP sense. They can also multiclass, which loses slots, but thanks to the items they have they can cover the gap easily. The lvl 3 and lvl 1 slot amulet was the result of some discussions with others; as none of the items can safely be worn all the time, I felt that offset their ability, as they each require preparation.
As for GMW, thats easily available from others. Righteous fury, less so; but the other stacking stat spell, aura of glory, is a lvl 2 spell for paladins. This would at least require finding a hopefully *very* rare amulet.
