I have to admit I both like & dislike DNC. I like how easy it is to do either single-target damage or a group-wide attack - for me the fact it generally has fairly few key-presses (even with doing the dances every 30-60 seconds) is good, as I have an disability which effects my reflexe's & reactions... so a ranged class that's easy (ie 1,2 with 3,4 as they light up, along with hitting the big AoE and fan skills when buffed).

The other main aspect I love about it is I feel like I can help groups out with it's utility. Dunno how much putting the shield up helps, or using the healing... but when I'm doing group content I always try and get my shield up if I see a group/raid/map-wide AoE coming, or if I see a tank/healer about to de I'll pop the heal by them to try and help out... or if we've just done a stack and all low on hp, hit the heal to help out. I get the same feeling when playing my RDM and I see healers down, hit the fast cast and rez. Helps my mind out as I know my dps won't be the best (ie see my issue's), so I like to try and do what I can (both RDM & DNC are in best gear I can, with +60 stat melds)

What I don't like about it is the aesthetic / look when you draw your weapon. I personally think it's pretty lame to stand there jumping up and down holding your weapons at your side. Really doesn't look worrisome / intimidating / etc when in a cutscene or something and your character inter-ject's between 2 NPC's to protect the 1 from the other. Admittidly this is the same issue I have with SMN & SCH as well... whipping out a book just.... doesn't look great IMO.
