Customization being free / cheaper

So a BIG thing I have experienced with many mmos going into late game is things become repetitive and die out . One thing that has always kept me glued to a game in these situations is great customization . I believe customization is so good cause you can set your mood for the day with colors / patterns . Having the customization be more easily accessible to players In my opinion would create interest in staying logged in the game for longer durations . Having to pay with character customization ticket with Royal crystals , a currency not obtainable through just playing the game is also kind of crazy to me . At the end of the day people want to be in their own mood in the game to enjoy it more and customizations plays a big part to many .
