i did a bit of limit break damage testing.

Last I knew it was based on weapon damage and your level and BRD/MCH have the lowest weapon damage in the game by quite a large margin.

It really could do with being slighty increased imo.

Dex ranged are just getting screwed over atm it seems.

It's based on the average WD of the whole party, not the LB caster. It's been tested where they changed the parties weapons, to lower ilvl and the LB caster used the higher ilvl.
