The biggest WTF moment was any that took place in the circus. I really hated these sections.

The second WTF moment was Gawyn pulling a "Matrix"-style combat scene in TGS. If anything convinced me that he was a psychotic loose canon, that definitely did it. He later goes on to try and intimidate Egwene into doing what he says after she has become the Amyrlin Seat. Hey, Egwene, if you have to ask your boyfriend if he is going to force you to listen to him, and you honestly don't know what his response will be, I tink you need to choose another partner.

Another WTF moment is Rand channeling the Shadowspawn finding killer weave in TSR, and then never using it again. He does the same with his freezing weave. All of these useful weaves are used earlier in the series, and then later seem to have been forgotten.
