They are about the same number of points, so which one would you take once Veers is released? A fully loaded AT-ST is about 250, and Darth seems to come in around 230 (maybe like these buildouts https://tabletopadmiral.com/legion/ ).
Vader seems better handled to take on Luke (immune to pierce, etc.), but the AT-ST can just lay so much fire down and has the mortar to get suppression out early, etc. Luke with pierce and impact seems like he could eat up the AT-ST.
Not sure. What are your thoughts?
