Having just finished Star Wars: The New Droid Army, found myself confronted with an interesting question. If someone haven't seen the game, I'll firstly write a brief summary of its plot - Anakin (the game's events take place almost immediately after AotC, directly dovetailing with it) discovers that Separatists are building new battle droids covered with cortosis which makes them lightsaber-proof. Then the Council orders him to go to Melatorn (where these droids are being made) and destroy the factory what he does, killing Count Dooku in process (the game was released in 2002 and developers didn't know what was Lucas going to do in RotS, so later the Lucasfilm retconned that it was not the real Dooku, but his clone). Per Yoda, the droid army made of cortosis-covered (and thus lightsaber-proof) droids is a threat that the Jedi (and the Republic since the Jedi then were a part of the Republican army) are unable to handle. Were the Jedi really that important for the Republican war effort? In AotC, Mace Windu states clearly that there isn't enough Jedi to protect the Republic. We don't know the Jedi Order's size as of 22 BBY (at least in Legends) so it's impossible to calculate the Jedi-clone ratio in the GAR. And let's not forget that after the Order 66 the Empire managed to take out the CIS remnants without the Jedi. So how really important were the Jedi for the GAR? Since the emergence of the lightsaber-proof battle droids doesn't affect the Jedi's ability to command the clone armies (in fact, Jedi usefulness as generals is also very doubtful but let's assume they are competent enough), I want this discussion to focus particularly on importance of the Jedi in combat (using their lightsabers and the Force), not their role as commanders, And yes, I know that the whole Clone Wars were a farce aimed at killing the Jedi. But Yoda obviously didn't know that before RotS' events took place so his appraisal of the Jedi's role in the war is based on premise that it's a real war.
