My MM build plus some thoughts
1) Drop signet of the locust. Feel free to swap it in during PvE when you need to run places, but it shouldn’t be an official part of your build, it is going to drop your DPS by a pretty significant amount, and one extra minion will far outheal it. In PvP MMs are terrible roamers (imo) so you don’t really need the speed.
2) In PvP, drop the staff traits for minion ones. In PvE its fine because of the utility and AoE damage, but in PvP you are only wanting single target damage, and your staff will fill the role of a utility weapon for the fear/condition transfer/poison+chill.
3) Drop the carrion gear, only use Axe/Focus. Staff will give you condition transfer and the weakness is good, but not as good as what Focus gives. Condition damage is bad with MMs, you either want to run full PVT, or some combination of P/V/T/Prec/Crit%.
4) In PvP, drop the Blood Fiend. In lowbies it will be fine, but the higher up you get the better Consume Conditions gets, because they can’t just kill a mob to prevent 90% of your healing.
