For tpvp, I’m still toying with new lockdown builds. I’m having good success with this one though:
S/P GS
Sig Heal, decoy, MoD, Dom Sig, MI
6/2/6/0/0
Halting, Sig Mastery, Power Block
Phant Fury
Ill Defense, Bountiful Interruption, CI
Zerk ammy, lyssa runes (strictly for MI condi clear), air+generosity sigil on both weapons
Play it like a phantasm mesmer (rarely shatter) with a focus on interrupts using MoD, signet, pistol and GS 5. Rupts are huge if landed, doing good damage, giving you boons, and CI+PB on the enemy. Before you heal pop your phants so you can pop a 2nd set immediately after. Basically keep them locked down while your phants shred them. It’s a little weak against heavy condi if you can’t control the fight, which is why I had to keep lyssa runes and the condi transfer sigil.
