I've been struggling on my witchdoctor in cool ranch, I just barely got by the silver stallion fight. I had to use henchmen to just scrape by the lagoonies. I feel like they are a bit too strong. EVery time I go through this part of the game, I always end up using a henchmen or dying several times. Maybe you could make them a bit easier?
Cool Ranch has already had a MASSIVE nerf in the past, so I doubt KingsIsle would do it again. I would suggest side questing and switching up your companions.
