at the very least raising would be cool. especially if renting choco's worked the same in this game as it did in XI...it could save a lot of time and money to always have a free chocobo accessable. and make it so choco's can enter cities and other previously unaccessable places. at the very least cities, i always thought that was kinda dumb.
the thing about them fighting is...well one of the things i liked about XI was that you were safe whilst on your bo. you could use the bo <along with sneak and other stealth spells> to get to places you had no business being at your level <whether for exploration purposes or quest purposes> so while im all for fighting alongside chocobo's, im iffy about losing the protection they granted in XI
perhaps they make seperate job called chocobo knight. that way your invulnerable while on a bo unless your a Cknight.
but if they DID go the other way and anybody could use them to fight. i dont think itd step on anyones toes. just make it so that they are far less effective as pets than avatars, wild animals, and wyverns. and make it so you have to do a certain quest and be a certain level to fight with them
or perhaps when breeding you can only have one chocobo. you can raise it for speed or power. if speed then its a riding bo and you can use it to...well, ride. if its bred for power then its a fighting bo and can be used as a pet <and chocoknight if they put that in there> to fight alongside with
