Gladiator crucible viable builds with necro/inquisitor

I know it’s still very early, but anyone have any ideas on potential gladiator crucible mastery combos/builds?

I want to try my Death Knight retaliation build in Crucible but for some reason my char can’t talk to the Master to start it up. Build is extremely slow since it has too much DA. It did survive full Bastion of Chaos clear without a single potion (a few times had 4-5 heroes wailing on my char, but again the 3K DA resulted in 67-70% chance to be hit). Need to remove least 200 DA and exchange a bit of retaliation for Vitality/Aether damage for Soul Siphon.

I want to try my Tactician Retaliator too. Since I already removed my points, it should be faster.
