I wouldn't count that Mats because that is making use of an exploit. Using exploits to skip bosses wouldn't make them optional. Regardless of that, my point still stands that Taurus, Priscilla, and Aldia are all optional and are not required to complete the game.

Luckystar, the Masterkey is available to everyone. Just because it is a starting gift does not render the shortcuts it provides invalid. Taurus is optional, and it is a common PvP practice to skip him so you can be invaded in Undead Burg.
