Despoilers squad and my thousand sons

Hello everyone,

I'll get straight to the point. I recently acquired the melee weapons upgrade box, but I'm not confident about creating a Despoiler Squad (DS) for my legion (I play Thousand Sons). I've read the profile, but I simply don't feel sure about making them. I feel that with the Thousand Sons' rules and their psychic abilities, they don't benefit my DS much. I'd like to hear your opinions; I'm relatively new to the game and often get teased for choosing Thousand Sons, mainly because of their psychic abilities
