Tony Mowbray was left ruing his side's missed first half chances after Bristol City came from a goal down to inflict a first defeat of the season on Rovers.
Rovers got off to a dream start as Charlie Mulgrew's corner flew past everyone and nestled in the net just 13 minutes into the encounter.
Chances came and went, most notably from Kasey Palmer, who hit the post, and Adam Armstrong, before Josh Brownhill equalised with a free kick just before half time.
Furlther goals from Marley Watkins, Famara Diedhiou and Marlon Pack sealed an emphatic win for the hosts, but Mowbray says the missed chances swung the pendulum City's way.
“I think from our point of view it was a case of missed chances in the first half. That could have put the game to bed," a downbeat Tony said after the game.
“I don’t think it would be exaggerating to say that we could have had three or four in the first half. It didn’t happen for us.
“They are a decent side, have attacking threats and we have to accept that and then went chasing the game which left us a bit inbalanced and that can happen with football at times.
“It can be cruel at times in the Championship, teams have attacking threats, good players and have to take this defeat on the chin and move on."
The score did flatter City, who were clinical with their finishes, but Tony says he had to risk going for broke at 2-1 down, with the boss utilising Joe Nuttall, Ben Brereton and Joe Rothwell to try and find a way back into the clash.
“We lost a bit of discipline for the third and fourth goals with so many attacking players on the pitch trying to get back in to the game," the boss reflected.
“The balance of the team wasn’t the balance of a team that we would normally be playing.
“There were four attacking players on and left ourselves exposed a little bit.
“I’ve done that all my career, sometimes you can lose heavily in games, it can happen in football at times, you either keep it quite tight and lose 1-0 and think ‘that was all right’ or you go and try and get back in to the game.
“That’s the nature of the game and they took advantage of that."
