If I take magic initiate warlock and then grab eldritch blast as my cantrip and hex as the level 1 spell, is that a good decision? It says you can only cast the level 1 spell once per long rest but if the concentration is maintained can I still recast it like I can with Wyll?

Or would it be better to just take actor? My charisma is at 17 so that’ll go to 18, deception will increase to 12 and performance to 13.

Not sure which way to go.
