Just curious why you don’t allow telepaths?
I can't answer for @Minigiant , but we had a Kalashtar in our previous Eberron campaign, and the telepathy was systematically abused especially in social situations. It is severely limited using the rules, but the limitations are actually a bit complex to track off, and the player could not be trusted to remember and apply them, which caused quite a few silly arguments. Also, the interference with spells is not absolutely clear.
