Of course that Luffy met Buggy before Crocus. Buggy is the second after Shanks but my point is, Buggy did not played significant role and impact in Luffy's adventure and development. Although I believe Buggy will appear again soon helping Luffy.

NHC10 is just another possibility. I did not mention Doffy acquired his awakening through NHC10. This is just a possible way for Luffy to awake his DF.
