I've read all and I totally agree to the 3 daemon engines for 250 points.
Same thing for the cannons of khorne (well, since I play netepic I always put them in first fire and did not count them as daemon engines anyway).
Fleshounds are good and I like them as they are, you lack speed with khorne and really need them.

The banelord & lord of battle are taking dust because they're not competitive at all, for their price, regular titans are far better. Don't know what to do to make them better and keeping the khorne feeling though.

The Hell Talon alone for 350 points is just bad. At first I thought it followed the forgeworld packaging so I took 2 for 350 points and it was already crappy and never played it again. I use mine for dreadclaw proxy now.

The core NetEpic Gold rules list Cannons of Khorne as having the daemon rule, so if you were using the standard rules, you couldn't put them on first fire. The only way you could put them on first fire was if you were using the SM2 rules, or perhaps some earlier version of NetEpic that I haven't read.

Would adding Furies to the Chaos list be an option? Personally I think using them as the same stats and price as Cultist Fanatics but put them int he Standard Chaos list as a support option would work. Maybe allowing them to deep strike to represent them being summoned?

I just didn't saw that they get the daemon rule, and played it "as before" SM2 style, that was a mistake. But I think it's more appropriate and will do it on purpose in the future (and with my catastrophic luck on the artillery dice, they don't stay long on the battlefileld anyway ).

As Primarch says, the rule will be removed from the Cannons of Khorne in any case, so just play them as you have been (i.e. they can use first fire orders), because that's what they're going to revert to.

A small addition:

- It could be interesting to obtain a Chaos Reward card when picking a standard CSM infantry company. At the moment, there's no interest in playing a standard CSM comp (except the terminator company) as others comp grants a better bonus card.

If the titan weapon cost are modified in the TL book, it will be needed to update the chaos titan weapon cost too in the Chaos Codex.
