I can understand why you'd think like that about Gray and Juvia, but I don't get your reasoning about Wendy and Gajeel.

Their parents were never the reason for them being part of Fairy Tail, so why would them being gone for good make them any more or less reluctant to be part of the guild than them missing did.

If anything them being gone for good instead of missing would work in Natsu's and Lucy's favour, since the Wendy and Gajeel no longer have a reason to just up and leave to search for their parents.
