Rovers stormed into an early two-goal lead courtesy of fine strikes from Markus Olsson and Nuno Gomes and looked set fair for their first away win of the campaign until a rally from the home side saw them turn the match on its head, albeit with some controversy.
From being so in control to looking like they were losing the game, Rovers were grateful for Ruben Rochina's cheeky back-heel six minutes from time as the game ended 3-3.
Speaking after the match the Rovers boss said: "I suppose when you look at it, it should be a point gained, but we are disappointed because we felt that in the first 30 minutes we were excellent and in total control of the game.
"Then I think the big turning point was the blatant foul on Paul Robinson, he can't come for the ball to punch because the attacker is jumping into him, so I think it was a foul and it was a big decision and it meant they had their tails up going into the second half.
"I've seen the incident five or six times and I feel that it was a foul. For their second goal Gael Givet is just about to head it clear and he's nudged in the back and that took him under the ball. It was a great finish but we feel that was a foul as well.
"So there big points today that were big turning points in the game, big decisions from the referee and we feel we were on the wrong side of a couple."
For the first half hour Rovers were irresistible, scoring two quality goals, with Kean paying tribute to the way they scored the second.
"We scored some great goals, especially the second goal as it was a great team goal with 15-16 passes. We worked the ball across the pitch and Nuno knows what he's doing by letting the ball roll across his body a little bit and opening it out his right foot. It was a class finish and a great team goal."
But after that point Rovers suddenly found themselves on the wrack, struggling to cope with Leeds' forceful play, particularly from set pieces.
"I was very concerned, we struggled to deal with them. We were far too open, especially from free kicks," added Kean.
"So we'll be drilling them in training all next week so they can deal with those in their sleep.
"We feel as though Paul Robinson wasn't getting any protection at the back post, we were too open, the spaces were too big and we were letting the Leeds United players run trough what should be a tight zone so we are disappointed with that.
"We know the problem and we'll work on that until they can do that much much better."
