FW models simply seem to have been purposefully priced out of Matched play.
This appears to be the case as far as I can tell, as well.
However, from what a mate told me, people were upset about the possibility of stacking all those minus to hit modifiers, which I mentioned earlier.
I'm curious if more people know about this, if it's even a thing in tournaments?
That's a lot of resources pooled into making a unit of Spectres so hard to kill.
A lot of sources minus to hit mods, like Conceal, Lighting-Fast Reflexes, Hard to Hit, etc, actually get STRONGER if you already have a source of hit malus.
Example: Let's say someone with 3+ to hit decides to shoot at a unit and you activate an ability to make it harder to be hit. This means that this person now hits with a 4+, reducing his damage output by 25%. Nice. Now, let's say that unit was ALREADY at -1 to be hit. That means he goes from 4+ to 5+, which means the ability you activated reduced his damage output by 33% instead. Since he was already having his accuracy reduced, further accuracy reduction hurts him harder.
A better way of putting this might be, -1 to be hit is not that strong against someone who normally hits on a 2+. But it is absolutely devastating against someone who hits on a 6+. This means, the more you can stack -1 to be hit, the more effective each subsequent stacking of it becomes.
Eldar have a lot of strengths, but a lot of super competitive tournaments rely on shooty gunlines that pour out incredible amounts of firepower. On top of that tournaments often have poor terrain coverage, making the gunline even stronger. Against that, something like -2 to be hit is very very good.
Example. Guilliman buffing some razorback spam will have those razorbacks hitting with 88% of their shots. However, against an Alaitoc Hemlock Wraithfighter, they will hit 44% of their shots instead (due to the way re-rolls interact with hit modifiers). This means their damage output is way lower. Normally, they would hit a Wave Serpent with 88% of shots, but a Vectored Engine Advancing Alaitoc Wave Serpent will only get hit with 44% of shots. Normally, they would hit your 10-Elf Dire Avenger squad with 88% of shots, but instead those Dark Reapers have Alaitoc, Conceal, and you burn some CP on Lighting-Fast Reflexes, so Guilliman's Gunline will only hit with 22% of shots!
Now, do I do this in games I play with my friends? Nah. I don't even play Alaitoc. But this stuff is potentially quite strong at tournaments, and when Craftworld Eldar players place at a major tournament, I expect (barring something new and surprising happening), them to use to-hit modifiers to protect themselves.
