I don't see a reason why you wouldn't do a stormstrike and then pop ascendance, free damage is always good.
Looking at your armory, you should replace Elemental Force for Dancing Steel, and drop Herbalism for a profession that gives you static agility benefits. I think there is a better leg enchant that you can get also.
Looking at your Elegon log:
You had 43% uptime on Flame Shock.This should be at least 95% on Elegon, and close to 100% on any other boss
Over a 7 Minute fight you could of had at a maximum 42 Lava Lashes, you only had 24
" " 53 Stormstrikes, you had far less
You only had 80 seconds of Fire Elemental Uptime, you missed 20 seconds of Fire Elemental Totem, which is a huge amount of DPS lost.
There are other things you can improve on, but these should be good points to improve on for a start.
