Don't Stop Dancing

I have made a weak aura helper that makes it easier to do this, especialy if you are planing to fast spam it just for achievement.

While the oponent is performing his dance moves, click the icons you see on the center of the screen.
When its your turn to perform. spam the center button that appears and that will execute the sequence you inputed.

edit:
Weak aura updated for Dragonflight ui changes.

You don't have to "win" the dance to get credit towards this achievement or First Dance, but credit isn't given when the crowd boos at the end.

Warning: Your character gets hit with apples and heckled by the crowd if you fail horribly. I was hoping for a fun visual debuff when I came out so other players could see my shame, but alas, there was none. If you do "just okay", there aren't any fireworks or anything, but hey - at least there are also no apples! :D

Just to add to this. I was trying to do all 30 in one day and of course, I made a mistake here and there. (I was not using any cheats/addons so I'm not sure how easy or hard it is to do with an addon.) You can still get a "perfect" score and get roses, etc, if you mess up a couple of moves. In my case, it was usually switching up 2 moves total. So, like on the hardest level, there are 25 moves and I got 23 of them correct and still got a "perfect" score to count towards the achievement of getting all 10. So "perfect" just means getting into a higher end of the third part of the bar. HOWEVER.... with this achievement, you just have to get to satisfactory and NOT perfect! It looks like that is above the halfway mark, but I cannot be sure on the exact point that you need. I missed 4 out of 25 to test it and did not get perfect, but it was still good enough for credit towards the 30 successful participations.

It's a doable achievement without addons. I say the color out loud and then hope my fingers click in the correct order when it's my turn. It doesn't always work.... ;) If you get frustrated, though, then there is an addon apparently that can be used, but I'd assume it's the same type of thing. Make sure you can click the correct colors in the correct order! It's not long in between the opponents dances and your turn. I think these achievements are a lot easier than sorting mail for other achievements!
