I remember when people used to put sentences and everything in their posts. It was a golden era.
The Bladesinger and the Battlerager are setting-neutral (having originated in the 2e products The Complete Book of Elves and The Complete Book of Dwarves (respectively).
Thought the Battlerager was complete garbage in SCAG it did not capture the essence of a battle rager at all mechincally or in fluff
The two I think they got right were the SwashBuckler and Monk of the Long Death
I like what I've been seeing so far, but do agree with the sentiment about reprinting content already printed elsewhere. ToA monster section is half full of critters from Volo's Guide. There are any number of other jungle-themed creatures that they could have used instead (Tasloi, other types of dino, etc).
Originally, yes, but they've since become so associated with the Realms that I don't think WotC really considers them setting neutral anymore.
I'm curious how the Bladesinger became "so associated with the Realms." In 2e they were a kit in a setting neutral book, in 3e they were a prestige class in a setting neutral book.
So even if they were somehow Realms-specific for the full half hour or so 4e was a thing that's a small proportion of their published history.
It's less that they're published as a Faerun specific thing, so much as Bladesinging as a lore concept seems to have a lot more baggage in the Forgotten Realms than in the other settings. Part of it might be that there's less Greyhawk in general, but I can't really find anything on how the bladesinging tradition affects its world. Eberron I find a piece that roughly says the Heirs of Dhakaan are an excuse to put them in your game, and that's it. I get the impression they have no real place in Dragonlance or Dark Sun, either, simply because of the way magic is handled in those settings.
So while Bladesinging might not have been published with a setting in mind, it seems that the Realms is the only setting that gives them a real place in the world.
Well in 4E Warlocks were explicitly devil bargainers, but they are not in 5E so I hope they keep them either or. I kind of hope they are in alternative "Expanded Spell Lists" for Fiend Warlocks, or Invocations for Fiend/Chain Locks. Although I know restricting Invocations based on Pacts was very heavily frowned on by the community.
