Let's take a look....
No weapon enchant and no 675 weapon.
Incorrect opener. You also didn't use trueshot (you would have had it back for the vulnerability phase).
Don't use explosive shots in ST unless you have a LnL proc!
Only use black arrow with precise shots! You used it a lot without.
There was a fair bit of arcane shotting when presumably you were doing something else, but usually steady shot is the right choice when you're not capped on aimed shots, even if you're focus capped.
Not much point multishotting when you don't have trickshots talented.
You skipped precise shots several times by casting two aimed shots in a row. Always spend!
