If there is one rule I want changed, its standby.
With the introduction of the clones, its just a royal pain in the Nute Gunray. My least favorite part (currently) is the standby unit hammering another unit, rather than the one that triggered the activation. It's super duper fun to have Dooku shot by the clone standby ball when a unit of B1s moves within range. Oh and I loved that put out an upgrade that extends the standby range! That's super fun and not oppressive to play against when playing against Clones and Panda Bear.
Nothing says fun like giant defence balls in a wargame!
Feel free to share your least favorite rule in this game we love.
Disclaimer: I love Legion and play it weekly. Just, ya know, she isn't a flawless lady.
