So I'm a long time 40k player, getting into AoS with my spouse. :). I like the feel of Old Hammer, so this is my place! Some of the new stuff is pretty cool, however.
So, among the Stormcast stuff, Prosecutors are looking very thematic and rad for Tempest Eye. But they actually seem pretty great on paper as well. 15" Fly and 3+ save on T1 is pretty solid defensively. The Javelins are 4 dmg 2 shots for only 90pts. You can trivially make that unit 2+ hit and wound at range 18". Seems like a great Single Unit to add that doesn't need much support, and can keep your Hurricanum screened.
The Hammer guys are really intriguing to me, though. With a Heraldor, you can rocket these guys across the table for a t1 charge from a chunky survivable unit. If you can get a Ghyran mage to boost them with +2 run and charge, you're looking at a 20" + 4d6 charge range. You can even shoot with the hammers for a CP if you want!
For a super aggressive army that's supporting them with Gyrocopters and Scrourgerunner Chariots, I think they can be pretty great as a push unit to gun up the enemy and slow them down in their own deployment zone.
Thoughts? Worth my cash?
