Yeah, in 2.0 they do mentioned Warriors of Light and even if you are a 1.0 player that still means there are other Warriors of Light out there.

It's just that for some reason our character became more special than the missing Warriors of Light. Perhaps it's due to collecting those crystals + us getting Hydaelyn's blessing.

Clearly there's a difference between having the Echo, Having the Crystal of Light (Hydaelyn's chosen) and Having Hydaelyn's Blessing. Speaking of which ... didn't we 1st get her blessing vs Ultima?
