Fire mage looking for log analysis

[Calypssai]

Please help me analyze & identify why I rank so low opposed to other mages in my guild. Here's my logs from last night's Mythic EN:

Just to add to this. I am not looking for anyone to pour through my logs in depth. I'm sure there is a blatant error that I am missing. I *think* it might be cast time & movement, but I'm not sure how to fix that. I just recently changed my UI up & selected the "queue action upon button press" instead of button release in Bartender. I am a hybrid clicker / keybind user. I click some abilities & keybind some. I move with my mouse & keyboard together (click + A or D to strafe & move my camera angle). I finally have my opener down, but my DPS rapidly decreases throughout the fight. Can someone just double check my logs for any blatant errors or point me to the right place to analyze my issues?

Took a quick look - can see the other mages have higher CPM (casts per minute)

This is probably the biggest thing contributing to low dps, not throwing enough fireballs....

More fireballs, more crits, more pyros, more damage
