The feast known as the Assumption or Dormition refers to the death of the Mother of God. To that extent, obviously we (Orthodox) believe it took place.
It is also celebrated as a feast because of the belief that, as one of the holiest of people, Mary's death assumes her reception into the heights of Heaven. The Orthodox believe this as well.
The main distinction seems to be a different approach to "official doctrine." The Orthodox church is less inclined to make any kind of official pronouncement on doctrines. In the case of very long-standing beliefs like this one, it is seen as a pointless formality.
The difference of opinion about the doctrine of the Immaculate Conception is one aspect of a disagreement about Mary's role in the conception and birth of Christ.
The RC church teaches that Mary was chosen before her birth to be the mother of Christ, and that she was made appropriate and worthy by being born free from all sin, even rendered unable
to sin according to many RC theologians.
The Orthodox church believes that Mary was a good and devout woman, but no more free from sin than any other human being. She was asked
to serve as mother of Christ, because of her holy life; she could have refused the honour and burden. Therefore, we feel that she was an active participant in our salvation, not just the vessel through which it was achieved.
This distinction can be seen in a tiny difference between the RC and the EO version of the Nicene Creed. The RC church, in its older Latin version, says that Christ was conceived "of the Holy Spirit, through the Virgin Mary." ("incarnátus est de Spíritu Sancto ex María Vírgine") The EO church says that Christ was conceived "of the Holy Spirit and
the Virgin Mary."
