Help with my frost mage dps

[Pio]

My guild is currently progressing through mythic NH and we only just downed Krosus last night. I'm fairly new to the frost mage and only have the Lust ring as my Frost Legendary. The thing is I cant seem to get over 75 percentile on the frost mage dps and I don't know what I've been doing wrong. If anyone could point me in the right direction, I would be much appreciated.

Thanks all.

You are losing 1 bloodlust by letting someone else lust on pull.

wow, I never thought of that to be honest. I guess i should lust, then ask for a lust or use drums around 2.30 minute mark then i can lust again right at the end.

But are there anything else i can do to improve?
