Sam Byram's second-half volley looked to heave sealed three shock points at the King Power Stadium, only for Michael Keane to nod in Martyn Waghorn's corner in the final minute of added time to level.
It was a frustrating way to finish after a spirited performance and despite Leeds remainign six points from the play-off spots, Warnock said: "Obviously it is bound to be disappointing when you concede a goal so late in the game.
"But despite that it was a great team performance and I was really pleased with all the lads. I thought we had opportunities to go forward all the time and goalkeeper Paddy Kenny also got us out of the cart as well.
"It was an all round team performance and I was delighted."
Warnock admitted he was disappointed with the "inconsistency" of some of
the decisions from the officials, adding: "I have to be careful because the last time I felt like this and said something on television it cost me three grand. But the inconsistency got to me.
"But when you are disappointed to come away with a point from Leicester it shows how far we have come. It augurs well for the the final 11 games and we have six of them at home.
"There are a few broken hearts and tired legs tonight and it does feel like a loss under the circumstances."
