If you are a casual player, then you have to accept that there will be some content that is not for you. That's just the way it is.

By the way, you can get by just fine in the game without a relic weapon. I'm working on mine, but in the meantime, I've cleared all but Titan and Ifrit EX and Coil up through T8 with the i110 weapon obtained via soldiery tokens.
