Count me in the "not interested in PoL FR" camp.
I'll buy 5e FR material, if it supports the 1340-1380 DR era, or if it supports the ancient eras in the 2e books like "Cormanthor, Empire of Elves", using the terminology and facts from the appropriate time period.
So no Eladrin pre-spellplague, There are several elven, dwarven, halfling, etc subraces in the periods that previously included them, etc.
Essentially: Canon but with reverse retcon (anything that was ever retconned is ignored, at least in the time periods where that retcon did not exist when originally published.) This includes redefining a creature, from changing an iconic ability to changing a creature category.
I won't likely buy 4e books that have alot of post spellplague material. I wont pay 45$ for a 300 page book if I can only use 200 of it - or if I'm going to have to tolerate 100 pages of what I have no interest in.
So give me continued support in the 3e era, and the 2e eras, and I'll buy your setting books.
Put alot of post-spellplague stuff in the same book as the pre spellplague stuff and you're actively trying to repel me.
Ideally:
- Post-Spellplague
- Pre-Spellplague
- Pre-TimeofTroubles
- Arcane Age
Keep them separate, and support all the periods, and I will buy all of them but the post-spellplague stuff.
Put them in the same book, and I'll be flipping through the book to see how much of the book was "wasted" and how much of the potentially good material was tainted by 4e retcons before I decide if it's worth putting money on.
