What were the objections?
Mainly how they handle getting magic items at all. Aside from potions and scrolls, you can't go out and buy any magic items. 5th is trying to stress "you don't need magic items to be great". They're upset because to them, and I'm quoting here, "hoarding treasure and magic items becomes irrelevant; especially getting gold because you can't do anything with it."
And that's the point of 5th - the system is focusing more on your character's abilities. They want when you get that first +1 weapon to be a big deal - no matter if it's level 5 or level 12. It's now entirely reliant upon the GM to decide if and when he wants to give out magical gear. My other two players love that; it makes treasure more meaningful.
