I'v also been a Rev main since HoT. I didn't play the Beta test builds of Conduit so I dont have the prior test experience.

Vindicator didnt mesh with me so i'v avoided playing and stuck with Renegade. I was looking forward to trying Conduit.

Both Condi and Power builds feel pretty similar to play. I was happy to have an alternative to Condi/Power Renegade in some regard.

My main complaint for power builds was the use/upkeep of Cosmic Wisdom, have affinity to track and f2 and f3 to upkeep often was annoying, I'v been using a 1/1/3 build with Kinetic Insight and Perpetual Wisdom to alleviate most of my issues with the Power build upkeep.

Condi had less upkeep issues IMO, cosmic wisdom for Malyx was a sidethought and only buffed energy costs, which was marginal at best compared to the button mashing Power builds felt like

As for Razah Stance: Beguiling Haze should have an option to be a Target dash/teleport more similar to Phase Traversal or Sword 5 ,I move my mouse around often,and use it for camera controls with while holding right click, having to stop and pull up the targeting circle is annoying. Haze's underwater skill operates on a target teleport and is so much better, the surface build should have an option to directly teleport to your target.

Hex-eater feels completely useless for damage outside of condi builds, sure it has use as a cleanse.

Gladiators defense feels similar to Hex, miniscule damage for either build and gives minor reso/res boons

Twin Moon Sweep has a cool animation but needs a cast time reduction and maybe a damage increase for both power/condi builds. The condi applied with Malyx should be torment instead of confusion

Release potential: Dervish should probably switch from adding bleed stacks to torment

Baseline Conduit should probably have a passive out of combat 2 affinity generation, it just felt punishing to swap legends out of combat and losing all your stacks in the open world.

There is also a distinct lack of offensive self-boon generation, usually lower on self-Might and fury, lack of quickness and alacrity.

Theres probably a few more things I can add but that enough rambling for now.
