Been lurking on this thread a while, thought I'd jump in. I'm a long time High Elf player (20+ years), and I've been mainly playing with my Elves, first as a disparate order army (which wasn't particularly easy against all the powerful synergies in the other battletomes) and then as 4 Cities of Sigmar armies.
When the Lumineth were announced in January, I was excited - so much so, that I spent the next four months looking for anything I could find on them! I've got a good chunk of them painted, though these are the ones I'd call complete (awaiting some more basing stuff to finish). Though I am going to also show off my Avelenor, because I'm pretty happy with it so far.
I've also had an opportunity for a couple of games! Currently 3 for 3, but it's certainly an army that requires a lot of thought! I've played 1000pts vs Maggotkin, and 2k vs a nasty Living City CoS army with a huge amount of crossbowmen, and 2k vs Nighthaunt.
