Jumping in with the abyssal reports, but I am chewing through the rest from the start.
Thanks for sharing, it’s a fun read.
These last two were interesting for me because I have a soft spot for abyssals (I started KoW with abyssals) and your lists are vaugely similar to my dwarf list, which is also MSU and relies on shooting (nudge, wink).
Two differences, though, is that I am fond of “versatile units” (i.e. that have ranged attacks and combat ability) and I have second line damage dealers (not a lot of damage, they’re there to finish things off).
I think your abyssal list could benefit from the latter.
You seen to struggle to deal enough damage, which seems to be a danger with MSU, so I think a combat capable unit would help your list.
It’s worth noting that you fared better in the game where you concentrated your shooting and got good damage on a few units.
Bane chant might help too.
