I doubt most of you are bad enough at "Boss Fights" to have found this out. I am
I thought this was amusing.
I'm playing through on MoC again, with the patch installed, and I came to the final stage of the Golem fight. I think a change has been made to make this harder because I was having considerable difficulties. In frustration, I just started killing things, ignoring the Golem altogether. Suddenly, I realised I'd wiped out the first wave of enemies. I'd always assumed they would constantly respawn. So, could I do this with the rest? Yes I could. I killed everything leaving just me and the Golem. Without his "retinue", he's a piece of cake to defeat
I'm not sure this will be a strategy for Demon Crusher, though
EDIT: Just finished the game on DC. It turns out to be a perfectly good strategy
I finished off The Golem with a WWI rifle
