I've been playing for about a week and I'm enjoying it. When I started playing I did the usual click through you do when you are given quests, you don't read the text, just follow the bouncing ball but eventually started reading what was going on and the main quest is actually pretty cool with an interesting story.
There is no grinding as such, you get bugger all exp from killing single mobs but there are a few instances quests which run at certain times of the day which yield excellent exp and gear. Unfortunately for us in the AEST time zone, those quests only run during the day (from about 11am to 4pm AEST) or very early morning (from about 3am to 8am) so if you're just casual and don't get to game much on the weekend (like me) your mileage may vary.
Having said that, there are instances which run all the time and plenty of other quests to do which keep you busy. I particularly like the way-point system which lets you set a way point and the game auto-runs you to the location, handy if your attention is often divided when gaming (like mine!). Quests are also point and shoot (i.e. the way points are hot spots in your quest log) so you _can_ set auto pilot for quests waypoints also if you want to, but you don't have to if you think that's cheating/boring.
Apart from that, the game looks gorgeous, there aren't many customisation options for characters (about 10 options for hair and face) but even the Dwarven females look great (as in, not a girl with a beard, or whatever hideous lump other games female dwarves). The environment is also very nice, mobs are varied, there's not much random agro so exploring is easy and fun.
There are my random thoughts, if you decide to play come join me on Lionheart server (PvE West), I'll be on as Wraa or Blee.
