It’s hilarious that they brought this up as a big part of the story leading up to release and it only being two scions and it more or less ending by level 93
Koana needed at least one more Scion on his side to be a real threat. Giving him one of the ones that went for Wuk, maybe one of the twins, would have been perfect for levelling the score - giving Wuk Krile, Probably-Alisaie, and You as co-combatants, and giving Koana Thancred, Probably-Alphinaud, and Urianger as co-combatants. That'd make it 4 to 4 in a dungeon, and could have been a really fun setup for a boss.
Another option that would have synergised extremely well with his ideal would be to give him Y'shtola. In fact that'd make his team a perfect LP - a tank, a healer, a phys ranged dps and a magic dps. You can't tell me that Y'shtola A: wouldn't be a perfect compliment to his team, and B: wouldn't have straightened his shit
right out with her experience from the night's blessed.
Or just, you know, giving anyone a single named combatant that doesn't come from the scions. That'd work too.
Really, my ideal DT is to have both Wuk and Koana as candidates, and join you for one of the first two feats each. then adjust the MSQ so you can choose after who is the candidate you're backing for the rest of the comp. At the end, the one you didn't pick forfeits to support the other in the Gulool Ja Ja fight, and then the winner nominates them as their co-host, same as the story goes now.
Edit because I found I've quite enjoyed watching some parts of the MSQ with this in mind: if you start mentally replacing every wuk lamat SPHEEEEEEENE with a vinesauce vinny SPEEEEN the MSQ improves tenfold.
