I do think the Jedi can be quite silly at times.
If I were Obi-wan or Qui-gon, when they were on the TradeFed ship at the start of TPM and the 3 shielded Droidekas attacked, I would have destroyed them.
How, you ask? When they have shields and were firing so rapidly?
Force push. Bam, they're all down. Shields can't stop the Force, you know. Just reach out with the force, find their computer core, and rip it out of it's sockets.
Fighting people? Use the force to smash their brain flat.
Fighting an army with AT-AT's? AT-ST's? Use the Force to knock them over, then use the force to send the downed vehicles sliding into the armies around them.
Fighting a spaceship? Mind trick the bridge crew to activate self destruct. Or if the self destruct sequence is complicated, mind trick them to drop the shields to their docking bay (make them think fighters are exiting), then fire torpedoes inside.
