This build reminds me of my own. I prefer Unhindered combatant. As for the gear I found as I run full Ascended Marauders with Daredevil runes. Judge all you want but that guaranteed crit after a dodge is nice.
With that said. Pve is almost no issue. You should be able to get out of anything nasty spots with no problem. Love the HoT content with my daredevil.
If you need to crank out more damage without changing your gear to much change to deadly arts and Crit strikes. You will notice an increase in damage almost right away.
