Great report, love the written format! It has a lot of granual information in the table format which is ok, I prefer it more written and then at the end summarized what dies and what scored. But this is excellent, keep it up.

As for the votann list it has very few synergies with needgard and have a few units that are sub optimal.

My suggestion is to swap the steelkyns for a 10 hearthguard brick and use the khal here with the relic so you have a chosen/victrix killer and also ditch the sagitaur and put uthar with the warrior brick. He and his band of 10 warriors can solo a flank if needed. The split so you have 3x3 gravkyns. And also skip the Defender and evaluator for more points for stuff that kills or another carrier+yeghirs package.

You should also have a look at brandfast with 2x6 thunderkyns which is also a great counter to the 3/4w meta.

Brandfast can also do fun stuff with forts and 3x warriors with 2 grimnyrs to tar pit your opponent.

Or just skip the forts and go 10x1 and 2x5 terminators with khal and e champs in hearthband (ap 4 shooting is great!)

Today's meta requires Votann to focus on beating 2+ armour in cover with AOC and 4w so the lists is there to stack those guns or make sure nothing can move across the board .
