No it isn't the only campaign.
As someone who tested Vengeance, the PvE in Cyro is considerably easier.

Given that I have heard conflicting stories. Is it true that Vengeance will be the only campaign remaining?
If so, I'll be mourning the loss of my tanky Nightblade. Also, it's going to be a pain to do the PvE stuff with Vengeance loadouts.

Don't get me wrong, I like Vengeance every now and then. But if it's forced...

It won't be the only one, but they close 3 of the other campaigns. Blackreach, NoCP and Below 50 get removed and everyone gets forced into Grey Host to 200+ Queues, or you play Vengeance. If you want to play with friends in other alliances? To bad, Grey Host is Alliance locked, so you either play alone or you play Vengeance. Then there is the Veterancy System, either you play Grey Host and get less than half the rewards or you play Vengeance and get everything. Completely your choice though.

That still makes it sound forced. Alliance lock is account wide right?

What about digging up treasure maps with alts from other alliances, that'll only be possible in Vengeance?

That was the point I tried to make. Of course its forced, not by removing the actual PvP, but by making it as unattractive as possible.

Or, as I alluded to above, just ride across the map in GH. You won't encounter anybody 99.9% of the time.

Implying that GH will have no queue and anyone can just jump in though.

The GH pop cap is 360 (120 per alliance). As we have seen from every Vengeance test thus far, the majority of the GH population does not play Vengeance. Many of them use Blackreach or BGs as a ‘waiting room’ while they wait for the GH queue to pop (especially now that you can’t start a queue from IC). They won’t have that option anymore.

Without a proper waiting room, this incentivizes people to afk into a wall at base so they can stay in the zone, blocking others from getting in. Even without that, the GH regulars will not be happy if they’re squeezed out of their preferred mode of play by new people.

Essentially if you can’t get into GH, then you’re forced into Vengeance. Some servers are quiet enough that that won’t be an issue, but more populated servers will cap the only non-Vengeance campaign.

I realize the devs said that they’d consider opening more campaigns if the queues were bad enough to merit it, but they didn’t mention anything if we end up with a circumstance where GH is poplocked with a 100+ queue while Vengeance is perpetually at one bar. That still shows there is space for people to get into Cyrodiil… but the demand is not met at all.

They seem to be assuming players who want to play Cyrodiil will play it in either mode and not care, but as we know there are a significant number of GH players who will not touch Vengeance with a ten foot pole.

Based on what? Forum posts?!

I go to Blackreach to check the Golden on the weekends. Will she be in Vengeance if GH is full?

The Golden was on the U50 PTS Vengeance campaign and was completely interactable.
