That Binding Coil of Bahamut is just the beginning of the raid instance? That there is going to be more whackier bosses or raids to fight?

That if without all those video guide and raid guides on Binding coil and dungeons, you will have a whole lot of difficulties to actually figure out the bosses mechanics on your own? Thus it can probably live up to the expectations of moderate raiders that BC is actually a very challenging dungeon? Not sure about the hardcore ones

Cause nowadays, am seeing lots of people posting like it's easy to conquer BC on forums. But if you come across these 2 thoughts, don't you think that BC is actually not that bad start for endgame^^

My apologies if i am new to the forums. Anyways my point of view is from a moderate raider, I understand that most people wanted a more complete game when it was released but I do think most MMOs they are sort of a lifetime game and thus they will never be complete in some way.
It'ss all just the beginning i feel
