I always find it both sad and funny when some poster wants to change the game to fit "there version" of what they think the game should be... all because they obviously don't have the will power to resist these boosts themselves. Oh.. gosh! Someone is "cheating the game" is the wrong attitude to take, seriously let others play the game they want too. If they want to use these boosts like potions to "game" the system ... just let them. They paid for the game too, so let them play it their way, after all you are not their DM. And you play it your way... just enjoy the experience, and try out different ways rather than critiquing the way others "might" play the game.
