For some reason, you seem to think that spirit warrior warhosts have an intiative of 2+. However, the compendium states the spiritseer and wraithseer adds +1 to the initiative rolls of the spirit host, so that would make them 1+ initiative.

Spiritseers and Wraithseers also give farsight. So that's even better overall initiatvie than even aspect warrior warhosts.

Either I missed something, or you have been playing EUK Iyanden where Spiritseers do not give +1 Initiative....

It's been a while since I played my Iyanden TBH. They were my primary army for a long while, but I'm rusty. I thought It was just the Wraithseer that did that for some reason. We can look into it - it's probably not neccessary to have, but it is fluffy. I know 3+ Init with the +1 has been discussed, what's your feeling on that instead?

Give me a few days to finish wrapping my head around the current states of the lists (and to get the stat sheets written) and I'll be less prone to these sorts of mistakes.

3+ initiative and +1 with spiritseer (who also gives farsight) is good for me. It's also probably the best option, balance and fluffwise. Only flaw is that it is a bit bitty.

A general Init 3+ for the Spirit Host with a +1 for the Spirit Seer being present would make this very expensive (especially with transport) formation very poor if you lost the Spirit Seer, say to a sniper shot or well place barrage. At the basic size this is likely to be combined with being broken making it most unlikely that the formation will rally.

My basic point is that the bonus initiative comes at some risk. Although I do accept that it is a great bonus.

If it is going to be changed perhaps you might make the basic initiative 2+ but give the Spirit Seer Farsight and a +1 to rally only, rather than a blanket +1 to the initiative (as at present). That would stop the auto-retain and leave the formation rather more aim-less if the Spirit Seer were lost.
