The Psychic Blast powerset makes me wish I'd made my Force Field Defender a Controller with Mind Control and Force Fields instead.
Sometimes it's nice, but usually it leaves me lacking. At lvl 32 I'm certainly NOT a damage dealer on any par. It even takes me multiple shots to drop mobs 20 levels lower. Mind you, since I'm a FF Defender most of my slots have gone for boosting my fields, but that's simply ridiculous.
