I hated how Lyta was treated by Sheridan in "Wheel of Fire". With all her power, she only became dangerous when threatened, and he, well, all of them, owed her the Universe for her actions in the Shadows War and the war against President Clark. She deserved some respect and a lot more support.
I hated the fact that no rogue telepath or Lyta never hunted down Bester and completly suppressed his telepathic powers-permanently! A taste of life in the mundane side would be a perfect reward for him.
