DRG should have a special quest called "how to use heavy thrust"

[Katchoo]

I'm sorry, but no. If you're level 50+, you should know enough if you cared a bit about it.

Oh yeah i mean sure, by level 50+ you should have worked it out by now through one way or another but my point is the game does not tell you to and it's not to ally obvious either. I don't think 'caring' really comes into it.
