I've just read all 7 pages of this thread and I think it's clear that most people think the nerf was too much. Some people are hard core and want a challenge in all aspects of the game, others want to run through a story and kick a little booty along the way. Both extremes are not healthy to BIOWare's financial future. Nor will they satisfy the average user. So I'll throw in my two cents as follows:
Before this patch, on my 65 Jedi Shadow (208/216), I could battle the Oricon Corrupted Bothrium Beast fairly easily by interrupting it. My companion would kill the adds and I killed the beast. Usually within 2 interruptions. I tried that today, and died repeatedly. I used the same rotation and couldn't get it down to 50% before I died. I think it is clear that more nerfing has gone into this release than just the companions. Or I didn't realize how much I depended on my companions. Before the patch, I never lost more than 25% of my health and killed it within 2 interruptions. Now I cannot kill the beast. I don't see the advantage to this much regression in game play on past content. I also, don't want to have to pair up with another gamer for such a trivial task, but the way it is, I'll have to. I'm sure you hard core gamers think that's silly, but I don't know what else to do. If this doesn't change, the game is no fun for me and I'll look elsewhere for my entertainment.
Updated: Ran my Trooper and he killed beast as fast as he used to. Problem is what happened to my Jedi Shadow and melee fighting...
