Every pair or straight has the same value, A2345 equal 10JQKA, 22 equal AA. Flush is a flush, full house is full house and so on...that way the dealt cards mean less. No card is higher than others. If one uses two cards of the hand and has two pair, and other has two pair using one of the hand, the player who uses both wins, straight, flush etc the same method.
The other change, already mentioned in the thread, is no rebuys or add-on. Keep the game fair.
