I will absolutely never really feel comfortable telling you the best way to do anything for a variety of reasons.
If you've been progressing in your Covenant questline, you may have noted that the pieces you got earlier are languishing in your bags because they're low ilevel, while the latest pieces are as good or better than Heroic dungeon gear.
If you managed to get your Renown to 22, then you doubtless finished your Covenant Campaign and have gotten your rewards -- such as an awesome mount, an LFR-level weapon (useful for those of us to whom the RNG has not been kind), and of course the satisfaction of some awesome cinematics.
Today you can get to Renown 22 and unlock your Covenant Campaign finale — and get a 187 weapon token
Do you lack the proper tools to hit things with -- in the grand virtual World of Warcraft, I mean?
I'm in a guild, and I raid with my guild when I can make the raid times.
Now that I have two characters at 60 and have started catching up on Renown -- level 6 today yay -- I'm really coming to realize I had absolutely no idea what I was doing when it came to getting my Covenant systems in place.
