Also to the OP: this is interesting! I speak Japanese but never looked into what the auto-translate was doing before (I don't think I've ever run into a Japanese speaker on Cactuar, one thing I miss about the FFXI days was the mixed-language servers!).

And yeah, explaining the usage/meaning of よろしくお願いします is tricky as it has a cultural usage that doesn't map 1:1 onto American English.
