I would prefer they took the path companion and make it like the one in FFXI that you raised from level 1 to cap level, you could give him/her gear to upgrade damage, healing, defense, whatever the role you wanted, it would add a lot and give you more options like if you dont want to use your chocobo or if you have it injured (if they add that option) you may call it anytime and in any case be more useful because will have several pseudo classes. Maybe with the same classes that we have now.
