None? I'd probably put a good number of them as a response to in-game issues, or even non-existant changes, and some have even been rendered null and void by later books.
So um..yeah, my mileage varied quite a lot. I'm not even sure if I'm even using the same form of transport.
But since I don't want to argue minutiae, I'll just leave it at that rather than try to refute anything.
Uh huh. A good number??? I disagree, but won't say how I disagree because that's minutiae. Whatever dude.
Yup, changing Eladrins to Elves fixed a big hole. As did forcing Wizards to use implements. Adding brand new races and classes to the core books filled many holes (especially because all players WILL play with all of the new splat books). Adding Spellscar and combining two worlds into FR and killing off the gods. Changing the entire Cosmos. And darn those Wizards for flying for hours at a time. Fighters cannot do that. Unfair! We don't want the entire party flying up to the Dragon's lair at the top of the volcano anymore and avoiding the plethora of encounters in the tunneled maze below. That was a real problem for DMs!
Sorry, but when you purposely won't support your POV, it sounds like you are talking out of your hat. Disagreeing just to disagree.
