This weekend's beta is a stress test. As for the bugs, I have no doubt that they have already been fixed. That being said, my issue with the game was never about the bugs. My issue with the game is that it is a tedious bore.
Anyone who has played through the tutorial will tell you that it is a long, drawn-out process. It's basically "complete a brief task and zone into another instance for another task". There's not a lot of fighting to be done, but there's a ton of stuff to read. Someone related to Tolstoy must have written the dialogue for this game. If you're into looting urns, crates and chests - you will love the tutorial. The only real benefit I got out of the tutorial is that it gave me ample time to set up key bindings and test them out. (Inexplicably, your key bindings don't carry over to your other characters, which is kind of stupid).
Once you make it out of the way-too-long starter/tutorial area, you start questing so you can reach level 10. At level 10 you can begin to enter PvP . . . in which three realms battle for keeps and other goals. If it sounds like Dark Age of Camelot . . . well, it's obviously what the developers were striving for.
As for what I look for in an MMO? My favorite MMO to date has been Lineage 2. I started playing that game at release. If anyone is interested as to why I liked that game so much, just ask and I will post my thoughts. I also enjoyed the innovations brought forth by Dark Age of Camelot (specifically the PvP), Final Fantasy XI (the sub class system), and Warhammer Online (public quests).
TESO brings no innovations to the MMO genre. Furthermore, from what I've seen, it doesn't really improve on any "standard" MMO features either. The game just fails on so many levels.
In closing, I don't have a problem at all paying a sub fee. But TESO isn't even "good" in the realm of FTP games, so why would I pay for something that's not only inferior . . but no fun at all?
