A LS buddy of mine did a little bit of testing, it may not be solid info on the matter but STR even outdamages DEX and PIE in WS and AA for ARC, again that testing was done with ARC! The ARC therefore seems to have three stats pushing his damage, while we remain with two - I think that is quite nice. Seems safe to say that STR > PIE on the LNC too (as STR > DEX/PIE on ARC).

But again, i was not the one parsing, my LS buddy was. He was parsing the moogle fight, maybe not the top environment to do those tests, but well i thought you might find that interesting.

Now i'm quite curious about the question where the soft and hardcap for STR lies.
