Items' secondary stats

Would it be so bad for the game if we could choose which secondary stat to upgrade? I think this change alone would improve this game so much, letting you experiment with new and maybe more niche builds. Maybe make the choice cost something like 5 buck per each secondary stat upgrade, so the total cost of a good maxed legendary item would be 20 bucks, which sounds reasonable to me. Maybe the number of secondary stats could be fixed at 1, 2, 3 and 4 respectively for common, rare, epic and legendary items. I know this might break some characters, but that can be solved by toning down some numbers. I don't want an easier game, I would just like that if I get an item with the right stats, I don't have to hope for the right secondary stats to be upgraded. Any thoughts?
