The result extended the Baggies' unbeaten league run from early January and Brunt believes it is crucial to their top-flight hopes that they continue to make The Hawthorns a difficult place to visit.
"We're looking to improve on the last time we came up and so far it's been an improvement," he told the WBA website.
"If we keep picking up points here and there and make the Hawthorns a fortress, we should have a good season. I think there is more experience this time.
"Last time we thought we could stay up but errors cost us and made life difficult for us.
"Experience counts for a lot and we've definitely got a lot more of that, especially with the boys we've brought in.
"We're quietly confident this season - but we'd take 17th now if you gave us that."
