Since you're in PvP gear its hard to comment on the gearing, but just from the Ultraxion log I can see the following:
- Your ES is hitting for a very low amount, you're on 12081.6 average tick (hit) while mine is at 14085.1. This either means your gear is alot worse (but shouldn't be 15% as you're 402 vs my 406, using 403 vish at the time) or you were missing a buff/debuff.
- I'm on more ES ticks than you, while I had a 20 sec faster kill (meaning you should have at least 9 more ticks). We both had 4 fading lights, so thats not the issue (unless you're wasting time pressing the button too early). I also saw you having 11 LnL procs vs only 9 of me, which makes this even worse! You are either clipping LnL procs or slow / not saving focus for ES.
- Your number of cobra shots is lower than mine (66 vs 63 while again you had 20 more seconds)
- Your number of arcane shots is higher than mine, this probably means you are spending focus on it when you should be saving it for ES? Ever notice you lacked focus while ES was off CD? If so, this is your problem.
- You got 6KS vs 8KS for me, depends a bit on how fast it goes down, but might also have to do with prioritization (and you should have more time there since your kill was slower).
The other encounters are a bit harder to judge since they depends alot on wether or not you're swapping properly etc.
