I actually enjoy the level grind in most games. I love questing. I did not enjoy the level grind in DAOC because it was highly tedious. There were very few quests (even fewer quests at high levels). Instead of fixing this, Mythic gave us the /Level command and Catacombs. Bleh. Most people will tell you that ToA killed DAOC. I am a firm believer that it was Catacombs and lazy devs who did it. RVR was awesome, don't get me wrong, but when you focus all your efforts there and ignore PvE your game won't have staying power.
There was no reason whatsoever for DAOC not to have enjoyed the same level of success as WoW had Mythic simply done what Blizzard did and cater to everyone. IMO.

I had a dream. It was an incredible dream. When I awoke, I had a huge mess to clean up.
