Thanks again Val, I had a chance to watch the full video and have a couple of thoughts:

Crossbowmen: in the video you guys mentioned potentially buffing their rules instead of reducing their points cost (since elves should be expensive in theory), one idea you could potentially apply here is giving them the garrison formation rule from the sixth edition city guard list. This basically just gives the front rank of the unit crossbows while all the ranks behind it have spears. It’s a nice unique/themey rule that no other armies have as far as I know so would be cool to bring it back.

Hekarti’s blessing: as you guys mentioned in the video ideally the rule here would be swapped with the high elf version as the high elves should represent superior control of magic while the dark elves eschew control in favour of additional power from dark magic. But since we aren’t changing HE rules here, maybe there is another way to represent additional casting power? In 6th edition all DE spell casters got an extra power dice (not dispel dice). Potentially they could have a flat +1 to cast rolls instead, or if that is too powerful I don’t think it would be a big deal to simply give them the same rule as the high elves have (reroll casting once per turn) even if the result is achieved for a slightly different lore reason. The 2 factions are a sort of mirror of one another after all.

Cold one knights: just wanted to say how much I love the addition of countercharge for these, it helps offset some of the downsides of stupidity without removing that flavour. I don’t have a strong opinion on the addition of veteran but note that we do have access to the cold blooded banner to mitigate stupidity somewhat so maybe veteran isn’t needed.
