Sorry for the derth of posts, I've been otherwise engaged of late. That said I for one am very excited for the new Adeptus Mechanicus codex which should be coming out soon, as well as the Skitarii book coming just before it. I'm interested to see whether this will be the first book which truly works to unify a GW and Forgeworld range as has been suggested by some to be the new model for the upcoming 30k plastic range.
After I bought my first White Dwarf in a few years (I had a subscription for over 10 years ago.) I was quite impressed by the rules for the Vanguard and Ranger units. Both are well costed, neither is brokenly good or bad, and they each have workable weapons with different mechanics between the units. The Vanguard's rad weapons are very neat, while they differ substantially from Rad weapons in 30k I prefer this version. The 30k rad weapon effect only matters AFTER a multiwound model has failed to save a wound it has been dealt by a rad weapon, which is situational in the extreme. The new "double wound" effect is cool, and it works well with the weapon's low str of 3 and high rate of fire.
Skitarii Rangers actually strike me as being the more conventional of the two units, as they are essentially just equipped with Kraken Bolters. A while ago I converted a bunch of Skitarii for my Dark Mechanicum army but at the time there were no rules for them and I used them as Adsecularis Tech Thralls. Right after reading the new rules I started reconverting them into Skitarii rangers, all it took was swapping the lasgun barrels on their guns for more Sniper esk ones and adding some scopes.
