I don't like spawning at all. I tolerate it and accept it in games where it's used sparingly, but not when it's used the majority of the time. I had issues with it in Mass Effect 2 as well, though they allowed bypassing them by moving efficiently.
I prefer it when enemies can receive actual reinforcements from different areas of the map. And no, I don't mean simply spawning them out of sight and making them move, I mean if they came from another room, then they came from there and shouldn't be present there anymore. I shouldn't go into that room and then face another 20 mobs with their reinforcements ad naseum.
I know Icewind Dale had this, though if it was scripted I do not know. Dawn of War 2: Chaos Rising's campaign also had enemies reinforcing from relays which you could capture and stop them from doing so, though some maps did employ random spawning. Other games such as Shadow Company featured this as well. I even want to say Fallout 1, 2 and Tactics had this, but I'm not entirely sure.

Your rebuttal is invalid. You specifically stated that you didn't like the spawn mechanic in DA2, implying that you liked DA:O spawning better, without saying why.
A better rebuttal would be you saying that you didn't like either spawning mechanic, and neither DA2 nor DA:O combat, but that objection would only apply to you, since others have already mentioned like DA:O spawns better, without sufficient reasoning, so the characterization absolutely is accurate in that case.
For whatever reason, I see this as "reasoning I agree with." Examples and reasons have been given all over the forum, I think everyone can attest to that all ready. I can go on to give entire walls of text for why on everything I've said in my first post of this thread, but it would just echo the explanations and reasons others have mentioned.
