Berserker is easy to solo. SOLO. ONLY. Berserkers can solo really easily pre-patch. In mutiplayer, if you dont go rambo, you WILL have trouble every 5 seconds because crawlers are ALWAYS THERE. IN SOLO, crawlers is EASY because you ca just out run them or make them miss you when they jump, then kill it.
However, if you stick with your freaking team, you get hit by gorefasts if you pull out your ranged weapon and try to due with that single crawler, or you get hit by the crawler and prevent yourself from hitting by those gorefasts. If your team is good enough to clear everything, you will be playing with your thrumbs before any scrakes or fleshpounds show up.
Anyway, you are the one who stand at the front line, tank damage when needed. So husks WILL be targeting you. And again, you cannot dodge crawlers and husks that easy like you are soloing. So it only means you are constanly taking damage. So, the resistance buff is for this purpose. However it makes solo or ramboing laughably easy. If you're the last one in the team and able to get away from the hell hole, your job is much easier but normally berserker is the first to die if things really gone wrong. (unless you are not doing your job, i.e. tanking, staying at the front line)
Its the core nature of the perk. Unless you totally change it, you cannot help much about it. Even rolling back the buffs, berserker will still be a really strong soloing/ramboing perk.
Also, now all melee damage is halfed. Basically you need to hit the head for a kill. And for sirens and husk, you need alt-fire head shots instead of primary fire head shot killing. And now scrakes' attack can only be interrupted once (and I dont understand why they call this "stun"...), you must use fire axe alt fire if you dont want to risk any of your health. If you are the only berserker in the team, basically it is hard for you to back stab those scrakes because like I said above, you are the one standing in front of the team. Over 90% of the zeds will target you. It just cost too much time to make the scrake change target and then back stab. Also, when you are holding fire axe, suddenly swrm of clot is threat to you. Simplay everything except your target is now your threat because you cannot swing the fire axe quick enough.
So, berserker who are willing to work WITH his teamates actually take quite some skills to play. Now you actually HAVE TO switch between your weapons. And each switch could cause you to get hit. You are just too close to the zeds. So, I would say the resistance buff is mainly for this reason. And why suddenly people concern so much about ramboing and soloing? Solo isn't hard in the first place. Berserker just being the easiest perk to do so. Like it used to be. And rambos are there since coop-games come out. You can do NOTHING to stop rambos if they want to. When you can solo, you can rambo. If this the how some people to have fun, who cares? And what can you do?
And people who really play berserker (I notice some people only play 1-2 perks and act like they know much about a perk they dont play just by "watching others to play") will notice how much skills is needed after the back stab bug fix. Not only you NEED your axe ALT-FIRE for scrakes, you also need to hit the head. Otherwise you are gonna get hurt. For the old times, you only need to kill tapping mouse 1 to keep the scrakes actually hit you while killing those clots and gorefasts trying to surround you. Now, you need to stun the scrake with head shot and then back off a few steps to see if you teamate already kill the gorefasts around you, THEN you can alt-fire again. And, YES!! Rambo and solo is laughably easy, like I said.
