I don't understand why everyone is so afraid of missiles+ with Warriors. If you think about our 4T warriors, and look at the 4+, 3W as more of an "organic" 2-3+, then it really doesn't become an issue. Small arms fire has similar resilience like the Terminator, with the same vulnerability to big guns.
Also, IF they are shooting missiles+ at your warriors and you have a Prime in the squad, he can merrily eat a few before you lose anything at all. Heck, purchase him as an 80 point upgrade to your warrior squad to add WS,BS and some resilience to s8-9, if it is really an issue.
The most obvious is for last. If they shoot them at my warriors, my Trygons, Tyrants, Tervigons, Tyrannofex.... ETC is merrily getting closer untouched. IF they have enough of them to shoot my big bugs and my Warriors I'm probably in bad shape anyways..
I find that although expensive I do like Lashwhip Sword+Death for the general support squad. Double Swords is alright for characters and multiwounders but you said you were after general. Just remember that they are slow, and sometimes don't see combat. IF you want to keep them cheaper, rending claws/deathspitters isn't bad either, expanding the opponents to light vehicles but limiting the troop killing.
Personally I prefer lash sword because it is unique to the warriors, and I think that I am going to get wings for my Warriors, because they are SLOW. I want them in combat, wings seem like my solution. It also frees up another Troop slot for my usually full troop.
