in the TT gravitic hooks simply allowed the buying of warden escorts rather than being forced to bring the warden itself...
custodians currently have the gravitic hook but cannot bring non hook versions resulting into overpriced escort spams...
a simple request is to give tau a non gravitic hook custodian priced appropriately for its cost...

also BBs are generally underperforming cost wise due to the LC spam and the eldar... might be wise to give a blanket discount to all BBs the custodian included...
