So your saying by 10th level, you would like each player to have gotten perhaps 5 or 6 potions, 2 +1 equivalent items, 1 +2 or equivalent item and nothing else? Why even have magic in your game at all? I can't imagine there would be many people out there that would agree with this.
My group and I really love games like this. We play in games where we may get an item at 5th level and end up using 7 or 8 levels later. We like items to be a bonus, not something that is necessary unless you are fighting a certain type of creature.
