I tried ESO at the start and the game play was fun, and solo wasn't bad. The problem with it, at least in my opinion, was they made getting into groups a simple matter of pressing a button and waiting to be put in a group with others, who may not even be on your server (not sure on that last part). While this is the direction many games have gone, including WoW, this pretty much kills social, multiplayer interaction.
Sorry the shitty attitude of the players has killed MMORPG's. Gearscores, elites attitudes, 'what can you do for me" are the real problems. I recently rejoined one of the old MMORPG's and did some groups, most fell apart when one user was slightly slower, was new so actually wanted to loot, etc.. The games are full of people who just rush alt's through content with no time to help new players who have never played the game. After this experience I tried a few of the others (EQ, WOW, EQ2, etc..) as they are all (well except one) free, pretty much the same in all of them. I watched people mad when a a run took 15 minutes. And yes any socializing was quickly nipped in the bud as it "slowed people down".
There simply is no place for people who want to actually play a game anymore, your ridiculed if you don't know how a fight works, you should have read it, watched it on Youtube and left any enjoyment out of seeing it first hand at the door. Since every MMORPG is the same game with NEW PAINT nobody has time for some talk, some help , etc.. MMORPG's are just full of the same people who where playing them 10 years ago, but they are much more JADED now, nothing is new, so there is no enjoyment even with new paint.
Just an opinion, and i can reinforce it with a quick trip into any game, get in a group doing a dungon/raid, say "I'm new to this instance so please let me know what i need to be doing" if you are not kicked, get no help at all, or get a few Noob comments, you got lucky.
