veretragna’s “Warpblade” ist still pretty good. It’s very similar to your setup. I’d recommend the updated setup by the original author himself. IMHO really well rounded, optimized build.
If you want more defense, you can keep your Serenity relic instead of Doom. DPS will still be good, but you get an additional circuit breaker. Contrary to the GT linked above, I also went for Conduit of warring wispers like you did. Altogether a very fun build.
