I agree with this.
I think people forget all the things that made EQ horrible.
1) NPC's eating quest objects, some of those quest objects taking months to get because of rare spawns/drops. Without a process of consistent GM help on those issues.
2) Watching horrible Z-Axis pathing bugs be fine in some instances (Dain), but if you exploited them in others (Warders) where it showed content blatantly not finished, the hammer would come down due to the embarrassment caused.
3) Gameplay was horribly stagnant.
4) Some classes during the leveling process would lose all functionality and become summoners/CR retrieval experts/Mana Batteries. Destroying gameplay fun for those classes in it's entirety.
5) Ridiculous bugs (believe it or not, usually caused by just shipping a product that wasn't fully developed) that existed for months. From mobs under the world conglomerating killing folks above, to unfinished loot tables and developer boxes. Just all around, shitty.
Obviously there are a lot more here. Don't get me wrong, still a fun game that I poured a lot of time into, but your statement here said it best:
The first of it's kind in a 1st person open world MMORPG. Once people took advantage of that and actually made a quality game, we saw what happened with those supposedly "market capped at 500k" sub numbers.
This is true, but you can't really fault the design of EQ because of bugs. Even though many of the best features were emergent gameplay, like kiting, FD pulling, etc they still turned out to be extremely fun gameplay elements.
I don't believe anyone wants the bugs, lost items, or useless classes back man. Folks just want an MMO that doesn't grab you by the dick and pull you from one quest to the next, fluffing you up with full gear for turning in 5 gnoll hide lariats.
I'm no different than the rest though, I went to WoW and loved that shit, working through MC and BWL week after week was fucking amazing. Even wiping was fun running back together as ghosts, trying a different strat and finally winning, getting that full T2 set. Hell yes.
After a while though, it got to be boring. People would just die to travel, AOE everything no CC, flying everywhere, it just wasn't satisfying. You realize that without the risk, where's the thrill? Without the hardships, the victories seem hollow.
Now everything is 10x worse than WoW. Vanilla WoW would be considered hardcore in today's MMO scene. I tried rift and swtor and they were just unbearably generic and boring in every way.
I actually like playing EQ. I mean I enjoy sitting there grinding mobs, charming, mezzing, fear kiting, I could do it for hours on end. It's still fun to me, so I want a modern version of that, along with the slow leveling, exp loss, meaningful travel, the works.
