I know this thread is pretty old, but I have someone that I play with now with a parser.

Before, I was using legacy control on the PS4, and I would parse between 250-260 without using the lock-on.

I started using the lock on, and it has caused a little bit of brain farting in terms of me being comfortable adapting to uncommon situation (which means I can probably push this higher as I get more comfortable), but I am now between 295-310 every fight in T6. So, regardless of my gear or skill (judge away), having all of your auto attacks hit via lock-on makes a significant difference in your dps.
