Joe Carlisle scored 30 points - a club high in the competition - and David Lemi grabbed four tries to equal the club record for tries in a game in the Amlin Challenge Cup.
"I was pleased with the victory," said Hill. "The only thing that disappointed me was the end of the first half when we had gone 31-0 up and went off the boil.
"We had a little chat in the dressing room, told them we had to step it back up and I was very pleased that the players responded to score just under 60 points and nine tries in the second half.
"We broke the record last week in Gernika when we scored 13 tries so there was a little incentive to get 14 today. It's nice to break records, not nice for Rovigo, but the players enjoyed themselves and what pleased me most is that we held onto most of the passes.
"I thought Rovigo were a better team than Gernika come half time, they were more competitive, and I thought we would struggle to get 80 points on them.
"But to the player's credit, those that came off the bench added extra pace and we scored some good stuff with offloading and handling. We were pretty clinical.
"David did more running in that game than he would have done for a long time," added Hill.
"His hamstring tightened up but he should be ok, we took him off because he was pretty tired."
Warriors can now look forward to a big double header with Perpignan in December and Hill is eager for that Euro clash.
He added: "We wanted to make sure that if it is close, in a head to head, then we will lead. That could be crucial.
"We want to have a quarter final and a home tie, you could see the players were working hard to do that.
"We had to get the five points, get a good points difference and that gives us a good chance of going through the group.
"We know Perpignan was going to be the big one. We would like to be top when we play them at home."
