Agreed. As someone who progged Dragonsong is currently progging Omega. While I do thoroughly enjoy these encounters for the most part, they are incredibly draining even on a lighter schedule.
Despite the legacy of good ole Pepsi Man, he's still a step down from Dragonsong and Omega on the difficulty scale. Far closer than any current Savage tier but the big issue that stumped people way back then is gear gating. Funny enough, mechanic wise, Liquid Living is more complex than most of what we see nowadays sans Ultimate. He was ahead of his time in a sense.
You failed to answer my question several pages back. How are you held hostage by what I or anyone else does? You even admit to playing the game primarily for the story aspect. So you and I will virtually never cross paths. In fact, I'd wager most of the people you've taken umbrage with will never be in a single party you're in just because we have differing interests. Therefore, I could be running around naked (without mods even) and you'd be known the wiser. So why does it matter what I do or even if I did have mods? Your "hostage" scenario is entirely of your own making. Neither I nor anyone else can ruin your experience unless you let us by concerning yourself with what strangers do.
All that said, they'll lose far more subs banning everyone using addons than they will from people opting to quit playing because people they don't even associate with may or may not use them. Especially as most addons have no impact on actual gameplay.
The fact you're saying this tells me you've never set foot in any Ultimate. Contrary to what some people think, something like automarkers in Dragonsong has a very small impact. You still have to actually do the mechanic and know how Wroth Flame works. Otherwise, you're dead no matter what. My group opted for macros we each individually pressed based on what debuff we got. Having that process automated would have been convenient, it'd have been a fairly minor advantage for us relative to the phase itself. I certainly won't deny it's an advantage but nowhere close to what you're insinuating. Likewise, triggers calling out xyz isn't going to make you understand what's happening. Personally, I've never needed any nor do most raiders. In fact, a good chunk of people who do use them do so on reclears because they want to turn their brain off after progging the fight for weeks/months.
Revealing hidden aoes is a whole different beast though. I'll grant you that.
At the end of the day, the point to progging should be for yourself. I couldn't give a damn if someone wants to use all three of these programs or if they drop $1,600 on a pilot. That's their business not mine. It doesn't devalue my own accomplishment or the fact I put in the time to learn the fights and be good enough to clear them. I care about my own experience not what joe smoe is doing.
