Do you use them for O or D? Honestly Vandor is underutilized without a taunting tank in the party. Preferably 2. But at least 1.
The team is not about damage, its about outlasting the other team while you peck away at them. My Qira team had 9 defensive wins in TW this week, but it uses Q STH Vandor L3 Yolo.
But if I were going to run the team with the options you mentioned, I would probably run Q Nest Lando Vandor STH. Save Yolo for an offensive team. The AI does not use his abilities well. With 2 tanks he is needed for damage but with 1 I'd run Lando for the AOE hurt.
My Lando is used as an offensive lead and is only 5*, so this isnt from great experience, but I would not G12 him at this point in the game.
Also, even at 3* L3 is boss when paired with Vandor. Maybe worth gearing her to 4* g10 and see how she does. But she transforms the team on D.
