Dragons coach Paul McGregor implied the Warriors' approach may have been a cynical ploy to break any flow or momentum the visitors built.
"They came here with a plan, they gave away a lot of penalties and defended their line really well ... whether that was part of it or not I'm not sure," said McGregor.
Warriors coach Stephen Kearney denied it had been a deliberate tactic.
"For the last six weeks, they've had a good run with how they've gone about things. They're the best attacking team in the competition and have a spine that's playing really well," Kearney said.
"We had to put pressure on them and that was through a bit of line speed and really going after them. But it wasn't our intention to deliberately give penalties away," said Kearney.
