I love it.
On main
Lets me freely swap my covenants on main, so I can help my team unlock dungeon perks no matter what. I can finally play my off-spec with my preferred covenant and legendary. I can gather grateful offerings faster, to unlock the last few mogs I want.
Mission table farming
All my table farmers received 2-3 more followers with the renown 40 boost and the soulbind unlocks. That’s 2-3 more missions I can send out at a time. On top of this, leveling a new table farmer lets me ding max level at high renown, so I can quickly get them to 71 with a calling or two, and unlock even more followers along the line. No need to farm Torghast for followers anymore! Just ding, research the table, and get going! Even better, I can boost all followers to level 30, and progress the table campaign much faster that way.
More gold, more materials, what’s not to love?
Alts
Talking about table farmers: the changes made to Threads of Fate is sweet. It’s finally worth doing those objectives, WQs and side quests, as they’re much more profitable than dungeon spamming.
I can also equip my newly dinged alt in Korthia gear and a 262 legendary within an hour or so of dinging. With the Valor cap gone, I could grind M+ forever and get to ~245-ish ilevel in about a week.
I can also farm Korthia for ~20k research / 10k rep an hour, and upgrade my conduits to max in short order too. Tried that on main, and all my off-spec conduits are 252 too now, and had a few paragon chests too in the process.
Having a +20-ready new character prepared within a week after dinging is sweet.
The Bad
Now, there are a couple of things that could still be improved, like renown being account, or at least covenant-wide, rather than per-char and per-covenant. Would make it far less obnoxious to play multiple covenants. It would be nice if the Box of Many Things was account-wide too.
It would also be nice if we had cross-faction play already, so I could go back to Alliance. But 9.1.5 is a massive improvement as it is, so I’m not gonna complain (much).
