So Drazhar is good on paper, but his bonus to the Incubi is moot at turn 3. He's also mad expensive. For his points, you're better off taking more Incubi, as mathematically they'll do better.
Also, if you want anti-infantry shooting, a squad of 5 Trueborn with 2 Splinter cannons in a Venom is cheaper and puts out more shots than a squad of 10 warriors with 1 cannon.
Those points you'll save from the changes will let you get some meaningful upgrades - Ossefactor on the Wracks (best MEQ killer in the game right now for its points), Electrocorrosive Whip on the Haemy and Acothyst. If you need to fill out your troops, Wyches are great for tarpitting big scary things with few attacks, like daemon princes or whatever. Or the standard 5 warriors w/ 1 Blaster in a Venom is still good, as you can split fire and drop them off on an objective late game if needed.
Yo ho, yo ho, a drug-fueled BDSM space-elf pirate's life for me!
Can I get a Roll Tide?
