Hi @CorvusGER and thank you for the report.
We've confirmed that Bastila's leader ability is working as intended and yes, Vader's "Force Crush" can be resisted.
I totally get what the mechanic should be. Your analysis isn't 100% correct though, it assumes that health and protection should be the same. But I digress.
Just the other day, I played a Bastilla squad and Ezra still had protection after at least 4 turns. Ezra should have his protection eroded after only a short while because he has both a rebel and jedi tag. It could be that Yoda repopulated that protection up through Meditation, but that's 30%, eventually Ezra would run out (plus 30 but minus 40 percent each round if Yoda's speed was that high).
One final question though, is the protection up from Bastilla based on Bastilla's protection, or the individual character receiving the bonus?
For Ezra, after 4 turns, he would take damage equal to 160% of his max health. The Protection Up buff adds protection based on a percentage of the character's max health, not protection. You can look at the mechanics for any protection up character on swgoh.gg (I think the reasoning behind this is so you can still give the buff to units with no protection). Since Bastila adds 200% max health bonus protection, Ezra would still have 40% left after 4 turns. If he had the 30% from Yoda as well, that means the purple part wouldn't be gone until after 6 turns. If Yoda went again during that time, it would add another turn.
That kind of answers your second question as well: It's based off of an individual character's own stats, not Bastila's...but the stat is actually max health, not protection.
