Bastilla and Jolee gameplay

I think there is a pretty big issue with some of the gameplay footage I'm seeing. CubsfanHan in his video starting at timestamp 5:09 shows Bastilla's lead ability in action against palpatine nightmare teams with Traya. Aren't jedi supposed to have 150% tenacity when they have protection up under a Bastilla zeta lead? how in the heck are the sith able to still put debuffs on the jedi after having to go through that much tenacity? its like that stat doesn't even exist. it has to be able to do something at least. it can't be that those sith are just that lucky that their debuffs are getting that small chance of being applied EVERY single time regardless of tenacity. It should be where the jedi just rarely even get debuffed while they have that protection up 200%. is her ability working as intended? I thought it was pretty egregious when Sion does his special ability and can't dispell the protection up 200% (good) yet is able to inflict pain on EVERY jedi.......really? all 5 of them? that has got to be pretty unlikely with all of them having that much tenacity. Sion doesn't have nearlly that much potency to bypass that much tenacity.
