No you dunce, I mean that will not always be the case. People will be trying to do it on all of their characters so eventually you will end up with a team full of people without ward of dawn, done it where we have all warlocks, just unlucky but we didn't complain, we just got on with it and done it. Bottom line, if no one is running the guardians or have not maxed your desired subclass (everyone starts somewhere) then they can't, does not mean it isn't so-able. If the option is there then obviously use it but if it isn't then tough; deal with it or be a coward. Take YOUR ignorance elsewhere;)
