Boss Paul Lambert felt his side should have come away from the Valley with all three points after a 1-1 draw with Charlton Athletic.
The manager believes Rovers were denied a clear penalty after substitute Simeon Jackson was bundled over in the box in added time at the end of the game.
After starting strongly, Rovers went behind on the half hour when Harry Lennon's deflected shot gave the home side the lead.
However an excellent cross from the returning Adam Henley saw Jordan Rhodes head Rovers back on level terms right on half-time.
Rovers had the better of the play in the second half, but couldn't make the most of the chances that came their way.
"This was always going to be a difficult game for us because they've just lost 11 goals in two games," said Lambert after the match.
"I thought we started the game brilliantly but we lose a goal from a bad free-kick.
"But we get ourselves back into it with an excellent goal. It was a terrific cross from Adam and a great header from Jordan.
"I thought we were the better team, I thought we should have had a penalty, I've seen it again and it is a penalty.
"We had to stop that rot we were in and in the last two games we have won one and drawn one. So we've got to build on that.
"I thought it was the best we've played in recent weeks. I thought we dominated the game down here at a hard place to play. That is the pleasing thing."
