We need wampas to fight.
And don't start talking to me about Galactic War - I used GW exclusively to get my 500 Boba contracts filled. In the time it took to fill 500 contracts, I found and killed a total of 2 Wampas in GW. There's a concept in ecosystems biology called "functional extinction". This is when there are so few of a particular species left that it is impossible, without artificial interventions, for that species to survive even though there are a few members left who haven't croaked yet.
Wampas are so rare in GW that they'd never find each other to breed. GW certainly doesn't have a useful population for wampa hunting. Heck, I'd probably be sent to prison if I got caught with a pelt from a GW wampa, they're such an endangered species.
We. Need. Wampas.
