Alright, let's break it down.
The big Warrior squad is just a big no-no. Compared to that, two separate units of 5 (both with blaster) would fare a LOT better, increasing your mobility, and spread your threats at the same time. And even that option is subpar; 5 Warriors with blaster in a Raider is probably the optimal choice for Troops ranged AT.
The Wych squads, on the other hand, could well do with buffed numbers. Maybe even merge the squads, since multi-assaults shouldn't be too hard to pull off. Gauntlets tend not to be worth it; those points are imho better spent on upgrading their PW to Ago (it is your main combat unit, after all).
Scourges are nice. However, at this pts level you can ill afford to consider any unit as sacrificial. Maybe take Reavers instead, or follow my sig and take another Warrior/Raider combo.
As for the Ravager: DLs all the way. Maybe even add another one since these are -by far- the most pts efficient AT available to DE. You might even want to add a second one - they are that good.
Last two things:
- Where does the Haemy fit? None of your Wyches can accompany him as it stands and they are certainly the ones most able to benefit from the Pain Token. Remedy this if nothing else.
- If you want cheap Venoms, consider Wracks (as Troops!).
