If You are at maximum range with Ravagers (36") then those extra 6" won't help You to deal with most ranged high strength threats such as railguns, lascannons and missile launchers. All those are priorities for Ravagers, but they also tend to have 48" range. So in order to hit them with Your 36" weapons You have to be closer to them and at that range the
NS won't be effective anymore. Your best bet is invul and cover saves.
Hydra gauntlet depends on dice and for the same price You can get an extra wych which will put out the same amount of attacks that You get from gauntlet per average. Shardnet and impaler at the same time help to diminish incoming power weapon/instakill attacks, which will ignore Your
FNP saves (after the first pain token) - shardnet is also good against dreads and enemy
HQs. I also forgot to tell that haywire grenades are pretty mandatory on wyches as well.
There is another cheaper version of archon with agoniser, shadowfield and combat drugs - good to go with wyches as well. Huskblade/Soultrap combo really depends on whether there as Monstrous creatures on the table or enemy
HQ willing to engage, whereas agoniser works everytime.
For 1000 points Bloodbrides are a bit overkill... In fact, I'd rather run 9 wyches with Archon (or even more cheaper - Haemonculus) in that Raider, and split the Warriors in two packs, each with a blaster, in Venoms with double Splinter cannons. But I dont wish to impose my 1000 list on You
