Would it be wise to save keys or to use keys before 1.08 comes to consul
I think 1.08 is a ways off yet for us console players unless I am mistaken.
Though I think it is a matter of preference. I would await feedback from the PC gamers on the new key system before deciding.
As you are probably aware with the recent chatter PS4 has only just moved over to version 1.07. So definitely a ways off.
