You also lose your own history. Trophy's and record wise in that world. It will only appear on your overall record on the top of your profile.
I have no love for mergers on account of the loss of history and will not stay in a world that is going through a merger. I'll wait 8-10 seasons until a history is amassed again. Also, the worlds that I dropped due to a merger were by and large in the same position as before within 5-6 seasons. Looking and waiting for 6-8 new owners to join.
