I read the ability descriptions initially, however, my mage can't perform combos alone. For example, freezing an enemy + stone fist? Not gonna happen. And I do not control other characters, so I decided to allow them to finish my combos automatically. Hopefully that's what they do, although I cannot be sure, it's all so fast that combat is a blur. (Me is a fan of slow, turn-based party combat...)
In DA:O it was easy to control the whole party and you could queue commands! In DA2 when I tried it you couldn't queue commands, and since characters finish what you told them to do at different speeds, they often started making their AI-moves despite my control. So I felt like I had no real control over other companions, at times I had it, at times I did not, and I couldn't predict when I'd have it and when they'd be doing their AI stuff.
I guess I'll try out doing what you did to enable normal pausing in combat, however, from the looks of it it's going to be a repetition of my brief DA2 experience. I can't quite remember why it was different in DA:O, but in DA:O I never felt like characters were randomly doing stuff out of my control, disrupting my planning. Maybe there was an option to turn AI off, in addition to an ability to queue?
And stealth in this game! I remember trying to use Cole to put a flag in the middle of two giants' favorite place to go for a walk. He could sneak there without an issue, but no matter what I did, other companions stupidly ran after him and got killed (that was an early level party). I even googled for this and remember how others said to use tactical mode to make companions hold position, well, that didn't work for me. They held position for a while and then ran after Cole anyway. Eventually I figured out that the party can just run away from the giants and they'd give up the chase, that's how I managed to put the flag over there, but it's so disappointing that I couldn't properly use stealth to do it! So now Cole only uses stealth in combat on his own. It's such a loss, though, I wish he could crawl around scouting ahead, since I always take a rogue anyway. And I wish the party could pass undetected among all those low-level trashy mobs, but that's too much to ask.
Sorry for rant, I just really dislike the combat and stealth and I really wanted to like them.
