One thing that always annoyed me when 3rd edition was introduced, was the fact that Chainswords suddenly became just close combat weapons, no better than a knife or club. The stories are full of astartes captains armed with chainswords, and yet in game terms it's pretty much always going to be worth at least spending 15 points on a power sword. I know there needed to be some simplification so it scales up, but that's just too much for me.

Does anyone else think that something really ought to be done about it? They shouldn't be as good as power weapons obviously, but something inbetween (perhaps rending). Otherwise, why would anyone go to the effort of making a complex weapon like a chainsword (or chainaxe) when a length of lead piping is just as good?
