For casting, this was before the playtest really got into high gear, but they were polling for what people's favorite casting systems(things like vancian, power points, whatever the truenamer did, etc). Vancian was pretty low in the polls before suddenly rocketing to first at almost literally the last minute with the total votes basically doubling in that time. The forums were closed and basically wiped several times with several accounts either banned or just gone afterwards when people bitched about it. After that vancian mainly stuck in as the staple casting system, basically what they already planned from the start.
Playtest Fighter was actually a pretty solid foundation. To make it simple, the Battlemaster Fighter was the baseline Fighter and while it had less dice, the dice refreshed every turn. Not a major change on the face of it, but it was a pretty big deal and the mechanics had appeal to basically every type of Fighter.
Wanted to play a tricky maneuver Fighter? Godspeed, you're all set to use those dice how you like.
Want to play a more defendery Fighter? Have a maneuver to block enemies, make getting at allies harder, and if you're feeling extra spicy you can hang onto those battle dice to really make your opportunity attacks sting.
Want to unga bunga full attack all day every day Fighter? Don't worry about those maneuvers, just take those dice and roll them for damage every turn you mad neanderthal
It was a really solid baseline Fighter that had a lot of room to grow and had that kind of rare design that managed to appeal to everyone who wanted to play Fighter.

Above is a link to the playtest versions.
I believe packet 5 had a level 20 version of it? It's been a while since I dug through it honestly.
