Worcester boss Richard Hill admitted life was "a bit cruel" after seeing his team denied victory for the second time this season by last-kick drama at Sixways.
The Warriors were undone by an Olly Barkley injury-time penalty against Bath a fortnight ago, losing 24-23, and on Saturday it was Gloucester's Freddie Burns who came up trumps to secure a 16-16 draw for his team during the dying seconds.
"A little bit of inaccuracy right at the end has cost us two home wins in the last couple of weeks. It is a bit cruel, and a cruel blow for the players," Worcester head coach Hill said.
"We should have had a couple of scores in the first 30 minutes, yet we just lacked that little bit of composure, but there was a huge amount that was very positive today.
"Our defence was much-improved from last weekend against Leicester, and we've created numerous opportunities inside the opposition 22. Now, we've got to learn to be more composed just to finish those chances off.
"The players are working hard and giving everything they possibly can. For me, there are so many good signs. We will get there.
"The players are absolutely devastated in the dressing room. We've played Bath and Gloucester at home and we should have won both those games."
Andy Goode looked to have secured victory for the Warriors just two minutes before Burns' leveller after Gloucester skipper Jim Hamilton recklessly pushed Worcester lock James Percival at a lineout.
Gloucester head coach Nigel Davies has seen his team collect a win, draw and defeat from their first three Aviva Premiership games, and he admitted Saturday's encounter had been a poor spectacle.
"It wasn't the greatest game of rugby that has ever been played," he said. "But from our perspective it was really important we came here and got something out of the game. There is a lot more to come from us. I wouldn't like to think we will play that badly again, but we've come here, got two points and it keeps things ticking over."
