For me the weakest part of DT wasn't necessarily "too much Wuk Lamat" - that itself is a symptom of the deeper problem, which was less reliance on the ensemble cast.

We didn't get enough twin banter. We didn't get enough conversations between people other than ourselves and the lead NPCs. Part of this is because of Erenville's taciturn nature; he internalized his emotions to the point where he faded into the background too much.

My favorite bits of, say, Heavensward, were when Estinien and Ysayle were arguing with each other, and Alphinaud was doing his best to stop them from grabbing each other's throats. Or similarly in Shadowbringers, when Alisae gets pissed off at Alphinaud and lifts him up by his lapels.

The conflict doesn't always have to be a bigger bad! It can be the personalities of characters clashing. Sigurd hating Moogles. Gerolt griping about Rowena.

The closest we got to this was the bullying from Bakool Ja Ja.... but he traveled with us for all of one zone, and by then he'd already heel-face-turned and was an ally.
