As for Wyches, its not pointless theoryhammer. The wyches 4++ invuln save and low cost is a major blow to tyranid MCs. Add in Raiders that still keep you below the MC's cost, and now you can move really fast (and over screening units!) to boot.
Persumed you've buff them up with all sorts of Wargear to a much higher point cost, right? But the argument does hold true on a 1
MC vs. full Wych squad basic - to SOME extend. But it isn't certain all the Wyches gets into
CC intact. The 'nidz heavily benefit from having lashwhips and
FnP from Catalyst aswell, which might turn the odds around in this case.
Say you get lucky and get all your lil' girlies into assault with a
MC, you still have to consider your chances of getting a single wound in;
- First to hit, which is most likely a 4+
- Then S3 vs. T6, which is 6+
- Then the 3+ safe
- Then
FnP on 4+
Actually, ten wyches and a raider, if you don't bother giving them any upgrades, comes out to the same price as the absolute cheapest
MC nids can take. Upgrade the wyches and they'll, as a unit, still be cheaper than any
MC, but can take off two of its attacks with shardnets, and will have have four power weapon attacks that wound on a 4+.
Aside from against hive tyrants and trygons (both of which cost significantly more than the wyches), they'll be hitting on a 3+. Assuming they charged they'll have three attacks each, meaning either 30 total or, with a hekatrix, 27 plus four that could be power weapon, poisoned(2+), or power weapon that wound on a 4+, not to mention the potential for 10 BS4 poisoned(4+) pistol shots if they didn't need to fleet before combat even began. They've got a 33% (better than 50% if sliscus is in the army) chance of having either reroll failed to wound rolls or +1 attack due to combat drugs. Then, for the target to have
FnP they'd have to be close to a tervigon, which had to have passed a psychic test and chosen that
MC to begin with (and considering the radically higher mobility the wyches have, especially with a raider, that means they can just target something else, like the tervigon).
So, we'll say they had two shardnets, and a hekatrix with agoniser. That's 27 attacks, with four that ignore armor saves and wound on a 4+, who'll strike first against anything but a swarmlord, tyrant (which they'll attack simultaneously to), or anything with lashwhips, for 150 points (not counting the raider to allow them to zip around the map, allowing them to be placed anywhere within two turns).
Prior to combat if they didn't have to fleet: 10 shots, of which 6-7 hit, of which 3-4 wound, and of which 1-2 slip past the armor save, for 1-2 wounds prior to combat even starting.
Against any
MC but a trygon or tyrant:
Regular wyches: an average of 18 hits (24 if you got adrenalight for combat drugs), of which three will wound (four with the adrenalight; 5.5 wounds if you got painbringer for combat drugs), and one will get past the armor (1.3 with adrenalight; 1.83 with painbringer).
Hekatrix: 2.6 hits (3.3 with adrenalight), of which 1.3 will wound (1.6 with adrenalight; 1.99 with painbringer), which ignore armor saves.
In return, anything but a tyrant or carnifex will have a single attack due to the shardnets, and those will only have two. That'll hit on a 4+, wound on a 2+, and then be ignored on a 4+, for a roughly 20% chance of inflicting a wound with one attack, or a 37% chance of inflicting at least one with two attacks (~4% chance of inflicting two). (Not going to bother covering every wargear combination the
MC might have, because I've already spent too long calculating all this as it is, and I don't know the tyranid codex well enough not to have look it all up.)
The wyches will do slightly worse against a trygon or tyrant, but are practically assured of inflicting a couple of wounds, have a better than even chance of escaping unscathed (and so will win the combat by an average of two wounds, meaning the
MC takes an extra two wounds if it's in synapse range, or if it's not it has a decent chance of getting killed outright in a sweeping advance), and all for less than the cheapest
MC nids can take.
Wyches aren't monsters in close combat by any means, but they are excellent tarpits for their cost, who are in most cases going to outclass whatever they're fighting simply through their defensive abilities (shardnets and the 4++ save).
Of course, deldar do have better options than pure wychs for chewing up
MCs. An archon with a clone field, soul trap, and huskblade, backed up by nine bloodbrides with three shardnets has roughly even odds of one shotting any
MC the nids can field every turn of combat, and much better than even odds after it's managed to kill one (since that'll double the archon's strength, meaning his attacks will wound on a 4+, and since a huskblade is a power weapon that means he's virtually assured of inflicting at least one wound, and thus inflicting instant death (and doubling his strength again, bringing it up to the maximum)). In return, the
MC will get
one attack (due to the three shardnets), and the clone field allows him to ignore d3 hits, meaning it can't even touch him (since the minimum roll is a 1, and the
MC will only have one attack), and has about a 20% chance of inflicting a wound against a bloodbride (who have the same stats as wyches, just more attacks).
FnP will do absolutely nothing in this circumstance, due to the meaningful weapon being a power weapon (that also inflicts instant death).
