I played a few matches with the newer units and while I don't know how well they work at a high level of play yet, they seem pretty cool. The stryker allows you to go heavy on vehicle factories early without giving up map control to a player that went dox. They're definitely not as mobile as dox, so you're still sacrificing economy for timing attack potential/pushing power, but to a lesser extent.
You can use the horsefly to take out small amounts of AA without committing a ton of bombers or going for a dox raid, which opens up enemy eco for easy bombing raids and makes bombing less of a "win more" tactic.
The Icarus was buffed, but I'd have to try to come up with a build order to see what the ramifications of an aerial raiding unit that offers more energy are.
Barnacle seems cool, naval pushes are much less of a huge commitment now, since it's easier to keep those expensive, slow Orcas alive
Once I know more about em, I'll try to write up a more in-depth post on the forums.
