He was forced to watch most of the action from the bench during the famous 15-6 win over Australia, while he was in the same position for the games with USA, Italy and Wales, starting just once in the 62-12 victory over Russia, helping himself to a try in the process.
Trimble's return to RaboDirect PRO12 action wasn't a happy homecoming as despite crossing the whitewash the Ulstermen fell to a 24-17 defeat to the Scarlets, to keep the province sitting on 99 victories in the Celtic League.
But he admits he is desperate to put his World Cup nightmare behind him once and for all and fire Ulster back to winning ways.
"I think I do have a point to prove but if I don't want to get side-tracked, I don't want to be doing anything that I haven't been doing," Trimble said.
"I feel like I didn't get as much game time as I wanted [in the World Cup], I felt that I was playing well enough to get it so I don't want to do anything different now.
"I just want to get out and play the way I was playing and maybe build on it and try and bring a little bit more leadership to Ulster, bring a little more intensity especially after the last few weeks when things haven't gone Ulster's way.
"All the guys coming back are going to bring something to it. The impact you can bring to a team's performance is probably minimised when you're on the wing, but whatever I can bring, I want to bring it and do as much as I can for Ulster."
