In my opinion, if it bothers you, then you won't be able to read as well as you want because your mind will be distracted by what you perceive as an "inaccurate" tool.
However, one of my close friends reads with what she calls her "Rescued Tarot". It's made up of cards from different decks that were given to her because the decks were damaged, incomplete or whatever. A few of the cards she found by the side of the road! But she can read amazingly with it, so I am of the opinion that the tool is only one part of the equation.
