Okay, the problem with Wargs as a faction of their own is that they were really just many packs, not one faction. However, Orcsa domesticated some of them, thus we have Angmar and Mordor Wargs. Wargs could remain "Gundabad" Wargs, for the sake of ease, but they would spawn, like you said and I said earlier, in packs with a leader or alpha, and not in an invasion.

As for invasions, see my comment way up above about them.
