Jedi with anti-sith abilities

I had no idea people felt so strongly that jedi shouldn't have anti-sith abilities. I just thought since palp and co. have clearly stated anti-Jedi abilities, it wouldn't be such a bad idea to add a couple of Jedi that have clearly stated anti-sith abilities. I appreciate the support from everyone who agrees, and I also appreciate everyone's different points and the validity of their arguments. However, this game isn't pure Star Wars. Otherwise, it would be dominated by the force wielders. Characters who are considered top tier, such as wedge, Baze, chirrut, boba, even thrawn (I've seen reviews he's the best character in the game; I'm not sold) would just be decapitated immediately by the saber-wielders. So maybe it doesn't make sense to those who disagree with me that the current Jedi could possibly have anti-sith synergy; it also doesn't make sense that any common soldier (I.e. Geonosian soldier, b2, even the likes of Leia and Han) could ever take on a Jedi/sith 1v1 and survive, which occurs regularly in this game. Remember what happened when Han tried to shoot Vader in ep. V? Didn't really work out for him.

Edit: Oh and remember Jango? Perfect example of my decapitation hypothesis.
