The thing I'm noticing is that every character's action skill is in some way defensive except for Sal's. I mean yeah, you get a health boost and regen with the right skills but you can still get annihilated because you need to be out in the open to get the most of the action skill.
Am I doing something wrong or does this class just suck?
You're doing something horribly wrong. If you're under leveled, go do some side quests. If your gear isn't up to par, check / farm the vendors. If you need a good corrosive weapon, go tip Moxxi for the Bad Touch or go get the Teapot off Tiny Tina. Respec, and approach him from a different angle if the set up that you're currently using isn't working out.. Keep a fair bit of distance against him at all times and take out his Shield Surveyors asap.
I'm not too sure what else to suggest since he should be incredibly easy. Good luck.
Wilhelm kicked me and my buddies ass the first time we fought him. Both died multiple times during that fight. All the other runs ive done though he went down super quick. No idea why we got so destroyed fighting him the first time.
