I played EQ a few years ago and the primary reason I left was that I just couldn't advance in that game. Like Urall, I'm a casual player who just can't spend hours and hours in the game on a regular basis in order to level, get loot, etc.
Most of DAOC is like EQ with with "annoying" stuff stripped out. Now, lots of EQ players love the annoying stuff - they call it "challenging." To each his own. EQ is a great game if you have the staying power to play it.
As far as bugs, compared to EQ (at least when I used to play it), you might as well say that DAOC is bug-free. If you die from falling, 99.9% of the time, you really did fall. On occasion, you might fall through the landscape or otherwise get stuck; it's happened to me about 5 times in 3 years.
Once in a while, a quest will break. DAOC fixes such things fairly quickly, and if it caused a problem for lots of players (which happened in TOA), they'll equip the NPC to reset it or provide the missing item, etc.
Customer service will eventually get around to you, but most times it does take a while. Fortunately, you probably won't need them much. I think I've only had to request CS assistance 2-3 times in my three years playing.
The good thing about DAOC is that if you don't want to pvp (rvr in DAOC), you don't have to; if you don't want to "raid" you don't have to; if you don't want to "camp" you don't have to; if you don't want to do quests, you don't have to.
