Those who feel seriously about this issue might want to take the time to read this entire post, despite its length:
This issue has been around for a while, but one factor people don't take into account is that there may be more weapons (which may be overpowered), but this does not necessarily require the inclusion of a new Zed or a Zed difficulty increase.
Weapons can be chosen in the Trader; the Zeds you play against cannot (unless it's a mutator), so those who clamor for a new Zed in the vanilla game are asking for something that once intoduced becomes a constant, rather than a variable.
Coming from a HoE veteran, HoE was definitely made easier by the inclusion of the M99 and similar weapons; any weapon that can one-shot an enemy like a Fleshpound does take away some of the teamwork challenge required to play the game the way it was intended as a CO-OP game.
Then again, this does not mean you have to use these weapons.
If you play in a group (which I heartily recommend as opposed to pub games) and you play with like-minded people, then don't use weapons you consider to be overpowered. If you insist on playing in pub games, I would welcome anyone with examples of public games in which teams actually manage to win Hell On Earth with enough consistency to warrant calling the game "easy" due to the newly introduced weapons.
As a matter of fact until the recent introduction of the new weapons, one of the most complained-about aspects of the game was that it was too hard due to pub match players having no clue about what they were doing and ruining games (the now-stereotyped Level 0 on Suicidal or HoE). If these overpowered weapons made pub matches "easier", I would consider this kind of thing welcoming.
Then again, if you're a group player like me, you have little excuse for rallying against weaponry that's overpowered when you and your team can simply refrain from using it.
The proposed solution of a new Zed would require a rebalance on all fronts, and would not take into account the fact that some people have a hard enough time playing as is. The Brute can be a pain on all difficulty levels, mostly due to its behavior. It's definitely a fun challenge (I tend to enjoy the occasional Brute game), but as others have stated, it can be a very annoying enemy. Reference my previous post for a more in-depth look at how this new Zed might effect gameplay:

Of course, you can have whatever opinion of the situation you like: you may hate the Brute, you may love it, but that personal preference should be cast aside when considering a change that will effect the entire playerbase.
Here's a solution for those who have a problem with the current situation:
Group Players
1) Refrain from using weapons you think are overpowered and ask your team to do the same.
2) If you like the Brute, favorite a server that has it or ask your clan/group to introduce it on their servers (preferably with a vote option).
Pub Players
1) Try actually winning HoE in a pub match first.
2) Create new challenges for yourself by using less powerful weaponry.
The great thing about Killing Floor is the amount of choice you have when it comes to how you approach winning games (and indeed how hard you want to make it on yourself). If the game's becoming too easy, don't fault the devs, the game or other players; try making it harder on yourself first. Again, there are plenty of ways to increase challenge for yourself without calling for weapon nerfs or harder Zeds. Here are just a few ideas that can reinvigorate the game if you've grown weary and need more challenge:
1) Run your worst perk with your least favorite weapons.
2) If option 1 is undesirable, try running HoE with your favorite perk reset to Level 1 by using the
Perk Replacement mutator.
3) Play with Friendly Fire set to %100.
4) Play with the
Bleed Out mutator
5) Play with the
Impossible mutator.
If none of the above appeal to you, you're on your own. The game has enough in how it's designed to ensure that the difficulty range is practically limitless. If you still have issues regarding the game being "easy", it becomes evident how little you're willing to go out of your own way to make the game enjoyably challenging for yourself. There are plenty of options out there that can make this game a formidable challenge for even the most seasoned gamer. You just have to have a little imagination.
