Have been playing D&D for 25 years. Got up to 4ed but didn't like it so have returned to 3.5ed. Have 2 PCs - Psion (Kineticist) and Fighter (both newly 15th level, having advanced from 11th level after recently completeing the Red Hand of Doom campaign). Looking for some advice on best options @ 15th level for both PCs so have decided to join this board to post questions.
