Help with Balteus

So I just got Armored Core after playing the souls games and I got stuck at Balteus. Coming into ACVI, I believed it to be skill based but it turns out that it’s more of a “find a build” type of game. After I good bit of YouTube videos, none seem to really work (maybe got nerfed?) and was wondering what the community could do to help me. The most I got to was about 30% but then immediately one shot me at 70% HP. Anyone got anything for me? It would suck to drop it, but I’m not spending another 3 hours on that boss just to deal with a fight I don’t enjoy.

If you are wondering about more individual things, here you go

• out of camera 50%~60% of the fight

• unholy amount of spam (c’mon Fromsoft, you can’t use our own tactics against us.)

• flame attack (80% ish) and rocket that does 40% of HP. These are the ones that always kill me.

• the shield takes awhile to get down and each time, I can get about 25% of the HP down.

I don’t mean to come off dramatic or whiny, these are just what of noticed with the boss fight and all of them combined just frustrate me every damn time.
