I think it was a
huge mistake to even allow Half-Elves to suddenly be
Bladesingers (which was very explicitly
not allowed in the original idea.)
I do not like huge retcons like this.
I'm not trying to dictate to others what to allow at their table; unfortunately, this alteration
is trying to dictate to
me what to allow at
my table. This change just grosses me out. And I see it as something that the Elves would be
absolutely furious about as a violation of something held sacred in their culture... and rightfully so.
Seriously, the
Bladesong was even called out in Mordenkainen's Tome as being a specially and uniquely Elven mystical martial art. Now it's just something that anyone can pick up, and that robs it of so much of its mystique it is revolting.
