Played a game yesterday, full Daemons, storm of chaos list with Be'Lakor and the Sisters of Twilight and full elves (no trees) facing off. It was a very evenly matched game, Right up until the last round of combat I thought I was going to lose with Slaanesh.
One of the biggest highlights was the Titilating Delusions spell. Had the sisters roaming the back of the board for most the game. It was a fun match. the amount of arrows flying at the Daemonettes etc made it extremely difficult to get across the table, but in the end, there was a massive multi charge with two (single rank) daemonette units with Be'lakor into the two dragons and a unit of archers. The only reason I won the draw though was the dragons focusing on Be'lakor instead of going for easy CR slaughtering daemonettes.
One question came up, Waywatchers can shoot through forests, therefore being over 2" within the wood, unable to be seen or charged. Is this correct? I ended up scaring them out of the trees with terror, but I had a ranked unit ready to charge them before that and didn't simply because they couldn't see them.
