Excog is a superior lustrate now, and it doesn't need to be a shield. At 800 potency it's not quite the strength of a critical lustrate, and with the more forgiving timer and cooldowns it's easier to use. It's true that it rewards thinking ahead and punishes reckless use, but that's not really any different from Deployment Tactics.

The big things is the Aetherflow trait, which is honestly amazingly ideal. It effectively shortens your Aetherflow cooldown to 45 seconds if you use your stacks, which is fantastic.

A stronger indom is cool. I wasn't aware there was anything deficient about indom but I will certainly celebrate it.

One of Fey Union's stupidest issues was corrected in that it no longer consumes meter if the target moves out of range, which is frankly a better fix than the tether range (which is also good). Fairy placement planning is essential in the skill use, but that's as it should be.
