My toon's name is Zhen-xing

I did that. I don't even try to engage her and use the green circles to damage her, but even after I do, I keep a far distance and she just force leaps at me or uses force siphon then my character is dead. I keep Force of Will in the vest, since it takes 2 mins to recharge.

If you use Force Cloak, it just re-starts her health all the way to full health, nullifying all previous hard work to take her down. I mean seriously, what sort of boss has this insane amount of health, can teleport, make you stuck (with a crappy 2 minute regeneration cool down time?), damage you from ultra-far away, and you can only use green circles to damage her? What the F........I'm on Jedi Shadow, which apparently is a useless class against Vaylin Spirit. Tried all 3 skill versions, TANK, INFILTRATOR and whatever the other one was. About to call in and cancel my subscription today.

Tried this tactic, doesn't work. Kept distance and she uses force blast, force leap or some sort of teleportation as you try to keep distance. Every time she attacks even after getting injured by the healing circle, she still basically kills you. And the Force of Will takes 2 whole minutes to regenerate and the Force speed skill tree to where it grants you immunity to all debilitating effects doesn't even work. ALL IN ALL - Poorly designed game. Bioware isn't get anymore of my money. It's just the cheapest boss I've ever play in a game, period. -- I've played against the Senator on hard level in Metal Gear Rising Re-Vengeance. Now that was a tough boss, but at least it was a FAIR, BEATABLE boss. I don't think Bioware listens to customers (only so much do they listen... and when they do, they listen to the wrong things, like getting a no name blogger to write the Andromeda story, like seriously, ***......or messing up on character design or boss levels). So screw them. -- And if anyone is wondering, I've tried beating her with Jedi Shadow on Tank Mode, and Both of Its Alternative Damage Modes. STRAIGHT UP GARBAGE. BioWare, you suck. Fire whoever made this boss combat design.
