For anyone considering this, be really careful and double check what you might lose if you merge accounts. I considered doing this but as I'm a mount collector, it wasn't worth it to me to lose all that work that in exchange for access to my spouse's old CE pets.
Also (and I could be wrong) but doesn't merging accounts also lock out one party from doing dailies in general, not just pet battle dailies? There's not much in the way of dailies this xpac but it's still a consideration.
