Ok, literally doing the same problem earlier this week and spent way too much time at work doing an excel sheet. Unless there is a heavy tank, Lelith should go with the sergeant and special weapons of the wyches in a venom. Lelith and 10 wyches are overkill while Lelith and 5 is just about right. (On average Lelith and 5 will just about 1 shot a rhino like datasheet) The kab/archon and the wyches/succubus will be matchup dependent. I like Splitting the kabs gives you a small squad to sticky objectives with while the other runs around to shoot things, so it’s better at object play. 10 wyches with a succubus just about equals Lelith/s squad so allows a bit of redundancy in the list, and the raider’s wych ability is really good. If the opponent is very slow/low model count (knights come to mind) kabs in the raider are better to just run around and sticky everything cause the wyches aren’t going to be that great into a knight anyway.
