I'm calling bullshit. I don't get it.
No you don't get it, and I have to wonder if you never played EQ or something? Either way, you are going off in the wrong direction.
First off, I couldn't care less about whether a game has auto attack or not. I don't even care what the pace you bash the buttons is either. I would prefer it to be slower, but if I have to quickly tap 1,2,3,3,3 just to kick off each fight, then so be it.
What matters to me is that in EQ, your focus was more on what is happening out your characters eyes, what type of mobs are you dealing with, what were they doing, and how many etc. You weren't focused on tapping keys and looking at things on the UI, you were looking at the actual world. The challenge came from seeing things happen and reacting fast enough and with the right choice. That needed both skill to be able to manually change the target and click the correct spell or whatever (there was no cycle targets key), but it also needed real experience of playing the game to know what to do, and there was no substitute for that. There were no ez-mode ways out of any of this. If 10 mobs attack and some dumb fuck mage starts area damaging them all, they will all aggro him and he will die 1 second flat. If the chanter tries to mez some too, the mages magic will wake up the mezzed mobs and they will be pissed off at the chanter. So that's a dead mage AND a dead chanter. Then there was major heal aggro, and tanks didn't have ez-mode 1 button clicky taunts, they relied on building up aggro and sometimes it wouldn't even be possible. So if a cleric starts unloading heals to try to save everyone, after the mage and chanter die, next the cleric goes down. Before you know it, it might have only taken 5 or 6 seconds, but some bad choices wiped out half the group. And there is no combat rez.
That's one example but I could probably give you a list of 20 others, (I think I already type that here once before). And it's all stuff you just don't get in games any more. Another thing I miss is that mobs often used to bail when they got low on health. And unlike modern games where all mobs die in 2 seconds, you sometimes can't just quickly tap your 1,2,3,3,4 and kill it. It really needed someone to snare it, and if you failed that, the mob could run out the room and down the hallway and down to the next level, and literally send 50 mobs back to attack your group. Everything mattered so much, it took skill, brains, and experience of playing the game. And although the spells and things took longer to cast and on the surface, it looks like a slower paced game, in reality it was as fast paced as any game out today, if not faster. There were reflex things you could do where reacting in 1 second, could save the day, but taking 2 second could wipe the group. And that's not even an exaggeration, it was just like that, because there was zero coddling going on, so so many things could easily go wrong.
And fwiw, you could still obsess over math if you wanted to, it's just that doing high dps was not even required most of the time, and could even be bad. Yes it was nice on a boring tank n spank raid mob that is glued to an uber raid tank, so you can just spam out your best damage. But most of the time, staying alive and being smart was the far more pressing matter.
Also, I like the combat log. EQ had a combat log, and sometimes we actually had to look at it. But all it told you was damage in and damage out. It didn't spell out things for you like "hate", whether a spell got resisted, where to run, and all that shit. You had to actually play with your brain and use your instincts and intuition on that stuff. And you could do the math all you want, you aren't breaking anything. Also, everyone already knew the best gear for their class, the issue was getting it - because unlike modern games, that was a long term challenge. People would take a week or more to get one new item. You couldn't just do a 5 minute quest and get an upgrade.
