ESO has a lot of good points, I'll admit. When there was a bug issue, I usually heard from a dev within a day, so bugs weren't as huge an issue to me thanks to that (even the bank issue, which they resolved and gave me more coin back then I had lost). Graphics were lovely at times, or gave the dark scene as needed. Voice acting, yes it was very good.
I think the issue that turned me off to the game in the long run, is the grouping aspect. In most MMOs I play, I love joining a party with a friend or two to do anything content wise. ESO rather failed in the party aspect. Example, if I had a quest and someone in my party had already completed it, they couldn't 'go back' in anyway to assist me. Their version of the world they see would be different from my own, as well. So unless they were exactly at the same spot in a quest as I, no help at all.
To me, ESO felt more like solo console game that just so happened to have other players running around. For those who like to solo, sure, you may like it. Wasn't my piece of cake in the end. Sub canceled and returned to GW2 over a month ago.
