Khador - how do I beat this list?

No he just has them there for the extra focus and cause he gets them for free. Their magic attack is also nice to.

I starting to think I really need to get X2

I don't think a beast heavy list is going to be a successful answer. Khador does jacks a fair bit better than we do beasts I think.

Zaadesh2 is an excellent anti-melee warlock. However, I've seen it first hand and on many battle reports where an all beast Zaadesh list fails because a single fast high def jamming unit from the enemy engages all the beasts and prevents any important countercharges. That's what the Kayazy will do. Things that can stop Kayazy-type units in the time you have to stop them would be Cannoneer, Catapult Crew, bloodrunners+tormentor, and maybe Orin. I'd recommend Immortals with Zaadesh because they can be a very effective defensive strike unit on feat. Not quite strong enough to threaten arm20 though.

Makeda1 with 2 units of Farrow Brigands under a task master can hit jacks really hard and her feat works on minions, so retaliatory strikes will be great anti-melee tech with them. Keep the Kayazy off of you with the afore mentioned elements and it could be effective.

This next part is only theory, but there are the Arcuarii. With Makeda1 and Zaadesh2, their defensive strike and retaliatory strike feats are a huge deterrent to all melee lists. Most of our infantry can't threaten arm 20 on either of those feats, though. Swordsmen mini feat isn't active on the opponent turn. Immortals get the closest, but don't work at all with Makeda1's feat, and still aren't threatening to arm 20 even with Zaadesh2. Arcuarii, however, are our faction's strongest retaliatory strikers and defensive strikers. Makeda1 and Zaadesh2 both have a lot of capability to deliver this usually difficult to deliver unit. These guys have a very good chance to cripple a system when the jacks are coming in especially under Zaadesh2 since I think they end up P+S14 on feat turn.

I'm not blind to the Arcuarii's shortcomings. Their stat line is atrocious, although that point being knocked off helps. Maybe I'm too optimistic. However, with these two casters, and into this matchup, they seem very solid as an answer to a unique problem. Both warlocks have ample means to protect them from range between clouds, quicken, and krea. Both warlocks make it so it doesn't matter if they can't do a shoot and drag or get a charging alpha off. They will die in melee for sure, but with these casters they will get their weapon master attack off anyway, and they still need at least a modest commitment by the enemy to kill.

Farrow and Swordsmen infantry might be the best option though, it's true. Can't quicken or carnage them though.

Makeda2 and the cats should be able to deal with this. Just don't let anything get to Makeda.

I've used this list to good effect:

Zaadesh2
- Soldier
- Despoiler
- Gladiator

Feat and minifeat on your engagement turn and try to take out as many heavies as possible.

hmm... rip them apart. Xerxis1, Tibs, Ferox, Immortals, Aradus Soldier. They are better at armor but we are better at killing stuff, especially in melee. Use his feat for an additional di on melee damage rolls and just tear him to pieces. Immortals on an auto 3 dice, 4 on the charge? Ferox pouncing for the same? our weapon master stuff roll 5 dice on the charge, INCLUDING Molik Karn! The only issue is needing Xerxis in the center of the action because of his 10 inch control range, but if he's fighting melee? he'll be bringing his stuff to you.
