Chocobos in general should really have a rework. They were a massive boon in ARR- their stats were much closer to our own. However, since Heavensward, and even more so now in Stormblood, the gap between us and them is widening, making our companions less and less useful. NPCs in MSQ are more useful in healing, dealing damage, and holding enmity than our companions, and you don't need to invest absurd amounts of EXP, onions or plants to get food buffs.

So while having the timer is a nice touch, it'd be great to see some care go back into them again (like stat/growth adjustment).
