See they go with new and awesome new models thinking "everyone will love scary new models"
But then we had kids saying "Oh I'm bored with these guns, I wunt new guns, I wunt lv7 perks, I want this I want that". Granted I'm not level 6 in all my perks yet, and I have not completed every map in HoE yet either. But as far as I know, creating a new weapon means it needs a purpose. The Mac10 was a back up gun for the firebug which was valid. But who else needs guns now?!?! The after the xmas update there was some balancing patches throw around I bit I think, we might expect that after the summer event when forum attendance will peak. I believe TWI will do balancing if they feel it is required, I have no problems with all the classes and in a 6 player game I understand each classes role, although soloing a hard game as support with a AA12 doesn't mean much, doesn't mean the commando or something needs to be buffed. A new Zed (The brute) - It looks like he's piss me off so he's a pretty good applicant to be put in the game, upto TWI tho.
Some people are on complaining because they have finished the game and want level 7 to give them something to grind for, then what??!? Complain you want level 8 because your bored? Eh some people.
I think killing floor is a really hard game, I like it that way. <3
EDIT: I love you tripwire, throw in some DLC for this even so I can give you my monies (and unborn babies)
