Same happens for me (Im in japan so I think its lag on my part) but I find the best rotation after your opener should be dancing edge (10% slash resist down) then shadow fang then mutilate. Always prioritize huton and when you get it Trick Attack. Other than that keep the dots refreshed as best you can. I have times where 2 dots have the same timer so refresh the one that takes longer to get to Ie. Dancing>Shadow>Mutilate. There are plenty of guides around if you need more help.
