I agree with 1 and 2 wholeheartedly, and with 3 up to a point.
To clarify, I loved how the old race/class combo would give a unique spell or two, it was really cool. But, regarding abilities like the dwarf's Fear Ward, some people would roll dwarf priests just for that only, and some guilds would force their priests to re-roll a dwarf for that very reason. I'd love to see race/class combo spell thingies return, but regarding that aspect I understand the need for them not to return.
I have confidence that if Blizz decides to have it return, they can hash out a system or new spells or whatever to combat that, but since I only know the old system described above I say we have to let race/class combos slide.
I am so for race and class specific quests though, and not the quests you get at level 20 to run a dungeon or two to get some bland weapon, quests that actually make you go out in the world and visit remote areas of the game, for example the old quest to get Warrior's Berserker Stance, that was an awesome quest.
