Guild Wars 2

Player should be able to name all pets in ranger’s pet collection.

When we change the active pets from the pet collection, the pet name must be retyped which is annoying. And keep the original default names as well in the collection window so that we may look at them if somebody else asks what is our pet; the original name is needed for wiki searches.

This has been brought up before on several threads. On one of them at least, the answer was given that they decided it would take up to much data space to store all the pet names.

From that thread: source

(In this thread the OP thought it was a bug, so the answers refer to that. The part about saving names answers your suggestion).

“This is actually not a bug, it is working as intended. It is not optimal, but to save the names of all of your pets (read: all of everyone’s pets) would require another large name database that ANet did not create. Currently the pet name feature saves the name in the slot, not the pet, so changing out the pet type resets the slot name.
Perhaps someday they will change this, but it is not a bug”.

“This is pretty much exactly what’s going on.
Tl;dr: we may change this some day, but it’s not going to happen in the near future, and it’s not a bug”.

Uh huh. So they don’t care to add the feature. Let’s not pretend storing a bunch of text is difficult.
