Shield probe helps

I really like Vector actually more so his personality. He's sweet, gentle, and attentive. Sounds like a perfect guy to me if you overlook the Killik thing.

I posted this in another thread about this problem. Here's my technique: I managed to beat him with a level 32 Sniper Engineer and Vector. Getting Shield Probe helped me a lot when my interrupts and stuns were in cool down. To get him to attack me I went behind him on the platform as far as I could without breaking LOS (next to that circular terminal behind his guardians.). I used Portable Cover + Entrench and then Suppressive Fire (That's what got him to attack without me being right on top of him). When he charged me I used Cover Pulse and attacked him as normal. You have to time your interrupts perfectly to get him. I died a couple of times, but the fight was more manageable, especially with Shield Probe because it absorbs damage for bit if you cant interrupt. Hope it helps

In my experience Suppressive Fire works to get him to attack you, I activated it behind him on the platform.
