I haven't had an issue with any of the relic grinds. I won't be doing any progression towards the SB relic, but that's because I wanted to do things differently this time around. Previously, I always progressed my relic instead of using alternative means to get stronger weapons. I enjoyed it, but one thing I noticed was that I wasn't running relevant content to progress it. You can light farm in raids, but I didn't start progressing raid content until roulettes were introduced, and by this time I have already completed several relics.

Even if SB did the relic like days past, I still would be going the tome/token route I am now. It's the first time I am actually somewhat caught up and running the same 8 and 24 man raids with everyone else. Gearing up through several means in order to hit min ilv is totally new to me since I was always able to just poetic my way to BiS gear for a previous expansion.

Also, I got a bit tired of glowy weapons.
