Isn`t that obvious as you guys make it look like.

If we get a drop from bahamut itself, that means we are going to fight bahamut itself, which is, honestly, ridiculous thinking about the diference in levels and such. Yes we have the power of the echo and all blahblahblah. Bahamut almost wiped out all the city states of Eorzea in 10 seconds.

Honestly, i think we are never going to face Bahamut, unless they go away with something like really cheap like a "small incarnation" or he "possessing" someone, which would be cheap and dissapointing.
