I think it's about equal based on playtime per role. Majority of my time pre-Stormblood was on Dragoon. I have 2,753 total commendations. Pretty sure that I had over 1k before HW, and I had only leveled DRG and BRD at that point, everything else I leveled up throughout HW...so going to say almost an equal percentage. It all depends on how others view you, and what you can do/bring to the party.
