I agree with this. Rockets have a reason for being restricted, but swords and GLs are probably the weakest of all Power weapons at this point (aside from Colony). Letting people use them both at once would be pretty interesting, especially in Crucible. Different sword archetypes would be cool, especially if they made new class-exclusive swords. Hunters could get the weaker, but lighter katana-type swords; Titans could get huge, slow and powerful two-handed swords; Warlocks could get ones with ranged abilities.
While I do like the concept of having class specific weapons, I think that there should be more swords like the Quickfang and the Crown-Splitter that aren’t exclusive to one class.
