diablo has always been more of an action game than an rpg. to me, it looks like they streamlined the game to focus on its strengths - loot and carnage, and they've structured the game to reflect that. i dont have any issue with them taking out skill and stat points as stat points were almost always str/dex for gear then all vit, and most character builds had you spamming one skill repeatedly.
now, with all skills available, and 7 variations on each skill and multiple skill slots, they are making the game a hell of a lot more tactile. its a clickfest, yes, but its a really fun clickfest - and that's all diablo has ever been. the crafting system will really solve the MF grind issue; instead of grinding bosses repeatedly for gear, you'll just craft stuff that scales with you as you play. if you don't think of this as diablo 2.5, its a lot of fun.
