I had a lot of fun with the game, although I didn't get toooo far. It's probably a bit more complicated than WoW starting out as far as skills go, since you have many more to choose from. The quest mechanics are fun, and some of the diversity in character class choice (dual class, etc) make things more fun. Hirelings are also good for filling in support roles where it would be nice to have a friend.
Biggest tip -- unlike WoW, moving while in combat actually decreases your hit chance, so it's best to sit there and take it until you figure out how to roll and dodge and so on. Also, I think arrows and such are able to be dodged by moving out of the way, so the physics of it is somewhat more realistic.
Did this game with a mate at release.
Played for a month or so.
Shit started pouring down on everything, talking updates here.
Nothing got fixed in time - major delays, lag, downtime.
And the fact that it's actually boring and dull.

I gave DDO an honest shot and I loved it for awhile.
What made me "shelve" the game, though, was that 90% of the dungeons felt they were the same exact things over and over, just in different settings. This was around mid-way through the leveling process I believe. I even got myself a months worth of VIP status to see if that was any different. I still found myself rolling new characters, getting to a certain level, and then getting bored and making another.
It just didn't have any lasting appeal to me.
