Oh, pvp gearing is currently broken, yes.
Well, the Covenant campaign also unlocks your soulbinds, and they take like an hour tops a week, probably less, and if you skip them for a few weeks, you can catch up in one sitting easily.
There are no daily grinds for renown. The weekly is super easy, and most of the time, you automatically complete it by just playing the game as you would. The only extra part is having to pick it up at your sanctum at the start of the week.
Not a lot less. One item less from the end chest.
Yep, which you’d do anyway if you would want to gear the alt, because of the dungeon loot. The vault is a nice extra in this case. If you wouldn’t run multiple m+ on the alt if it weren’t for the vault, then said alt doesn’t need multiple choices either.
You’re not forced to, it’s your choice how powerful you want to keep your alt.
It gets easier and faster with gear. I usually finished layer 5 of a wing in 30-40 minutes on a resto druid in ~heroic dungeon gear. That’s enough soul ash for a R1 legendary in two weeks, R2 in two more, at which point you’ll likely be able to clear layer 8 in the same time on an alt too. Slightly slower soul ash acquisition, but we’re talking alts, not second mains.
In contrast to Uldum and MoP zones, Torghast doesn’t require as much travel, and there are no dailies.
You can be geared enough to do raids, m+ and pvp at a reasonable level without your alt being at the same power level as your main.
Yeah, don’t be like those people. The vast majority of people don’t need to have 5 mains. If you do, then yes, you’ll have to put in more effort. Still less effort than in any of the prior expansions, mind you.
You don’t. Conduit upgrades come from doing harder content. The item you can buy for Stygia is for the late game when you can’t spend it on anything else, and you want to collect / upgrade all the conduits, even the ones you don’t use. That is its purpose. You can spam M+ endlessly, and get conduit upgrades far faster than doing your daily Maw grind (where you have limited time anyway).
Sadly, yes. From a PvP point of view, Shadowlands isn’t looking too bright right now, I’m afraid.
