No Power Sword mentioned there. Also the way I understand it is: those weapons deal that charged extra damage to first elite etc. So you can still pick them in horde. The charge used to be dealt to the first enemy hit. So that change was a buff.
I feel like I have to reiterate, so here it is. Power Sword is not a bad weapon, no weapon is unplayable. It is just not fun anymore. It does suck. And yes, that is MY humble opinion, in case this was not obvious.
