Anyway, I've been watching shinsen-subs with a friend of mine and so far it's pretty good. Despite the title, it comes after the last series, the name of which I've forgotten.
There's a 'new' version of "The World" with completely different character classes that has apparently been around for a while. Currently, "The World" is full of PKers and guild rivalries that make it extremely hard on newbies. This story revolves around a black multi-weapon newbie named Haseo who decided to try the game because a bunch of his friends said they'd had fun playing it before. After getting PK'd he's rescued by Ovan, guildmaster of the Twilight Brigade. Haseo takes an interest in Ovan after this, which peaks the interest of TaN, a rival guild.
Don't worry about that site because all they did was youtube their anime you might as well go to www.youtube.com and search for specific anime. You can pretty much find any anime series on youtube.com.
Anyways, as for .Hack//Roots I actually enjoy this show but I've only watched like the first 4 or 5 episodes. The pacing is really slow as per typical beetrain style (I really wish bee train would do something different with their shows) but thankfully it still works for this show unlike other bee train animes. I'm just looking forward for the end of the series because this is a prequel to the new .hack game and the trailer for that game looked incredible.
