I just wanted to bring this thread back now that we have the PH available. Here are my concerns (I would like to make a great sword wielding warlock).
1) The Battle Caster feat mentions having ANY of your hands occupied
2) We are allowed one free action to do something small such as grab a component, but do we then have to put it back? I guess this could be avoided by having a crystal around my neck on a chain and i can just drop it after, but what about valuable components which do not get consumed on use? Remember, it's one free action during movement OR action.
I guess I'm just wondering if i absolutely need to take Battle Caster.
