*sniffs* I smell... *sniff sniff* a troll.
As far as I know, it has never been a part of the game and I've been playing since closed beta on IA. It has been discussed many times and has it's almost always been agreed that it wouldn't fit well with the game.I have no recollection of a sword/melee weapon being part of Legions, however I never played it back in the InstantAction days so who knows. Yes, it has been brought up several times before. Seeing as no one is developing the game I don't see this idea being implemented.
