Rand still does insanely stupid things. At the end of ACoS he runs off alone to kill Sammael & nearly dies half a dozen times before Moridin(!) intervenes. That retinue of Aes Sedai was probably the best thing to happen to him. He nearly died numerous times without them in APoD. He would have died at the end of winter's heart if he tried that alone with Nynaeve like he originally planned. He'd never have left Far Madding.

The other two also do stupid stuff (well, Mat more than Perrin), but it's easy enough to argue they shouldn't be running around loose either, not this close to the end. They have no real protection.
