Beating Demons in 40k

Since there were 4 of us at Patriot Games, for those of you who haven't played Demons before, here's what I worry about:

1) Go second. Kind of obvious because there's no Demons on the table turn 1, but if possible, go second. I recommend this in general for objective scenarios in any case.
2) If you have a lot of scouts, go first. If I play another Demon player, I'm going first if possible (and I'll even try to sieze the initiative). Why the difference? Every Demon has to deep strike. If you can spread out a lot, it minimizes where he can come down, and in all likelihood he'll need good dice and/or a hit to not roll on the mishap table. Spread out a lot - it hurts more than is apparent.
3) Demons deep strike. This means they can't assault their first turn, and that you can react to them if they don't shoot. This is another reason I try to go first against another Demon player - I can charge their arrivals first. In most cases, every Demon unit is better than it's equivalent in another army. This is more than balanced by having to Deepstrike in. Take advantage of that by picking them off piecemeal as best you can.
4) Shooty demons make Tau look good in assaults. Seriously. A Horror of Tzeentch has 3 BS3 S4 AP4 shots per turn, but is WS2, T3, 4+ save. Flamers are T4!
5) Almost no Demon gets grenades. A Bloodletter may have great stats, but with his save, him charging you in cover means you'll cut down a lot of them.

Anyone else have something they'd like to add?

the game i had against demons i used the terrain to make sure it was hard for them to get me without mishapping(of course then he rolled 5 hits.....

The biggest tip I have in dealing with Daemons is to shoot them.

Yeah, yeah, I know - not really a tip.

Where the tip comes in is shooting them in the right order. WildEyedJester is a master at weakening/wiping-out just the right unit of mine to keep me from getting a foot hold.

Another thing to do is make sure when you are going to start shooting at a unit that you have enough firepower to put it down. It is usually better to destroy one unit than to weaken two units. A half full unit of daemons will still mess you up about as bad as a full one most of the time. When Jester is shooting my stuff to bits and one is left standing I will often cackle and holler out 'All it takes is one!' and then he will often times shoot it with another unit or tank just to get rid of it so it doesn't trounce across the field. This is especially true of Fiends of Slaanesh or a unit with an Icon.

One last tip - man I'm giving away all my secrets here - never give up. I have had my Greater Daemons killed by Rhino and Drop Pod bolters more than anything else. It is usually a last ditch effort to knock off the last wound, but sometimes it works. A wound is a wound, all it takes is enough shots and they will go down. An extra four or five crappy shots a turn from transports will add up.
