Well, I have mine set to pause for everything when I solo (and I forget to turn it off when I multi, much to the dismay of my fellow party members). But I like to have time to think and work out strategy. I guess I am more "turn based" in my playing style. I do when I solo pretty much assign action to each character. That's the way I play. There is really no right or wrong way, just individual preferences and playing styles. You might to to experiment and find what works best for you.
And BTW, welcome to the board and check out the General Discussions sometime, too!
