I'm curious how much of that is intentional, consider the boss difficulty as bands - pre Curator as (and this is all relative within Karazhan, I mean no offense) "easy", Curator/Aran as a discrete step up to medium ("gatekeeper"s, if you prefer), and after as "hard."

Not to derail this isn't a huge discussion on the merits of what's harder or easier, but to just sort of broad strokes look at perhaps why the respawns there are so long. If you're in the "easy" bucket, and you're spinning your wheels trying to get over the bump, throwing loads of time at the problem isn't going to just magically make it happen - the trash significantly slows you down in this regard.

That's my theory on why Aran's trash is as it is, and why it juts out as the numbers provided.

But it is pretty brutal, especially considering (and feel free to thrash me for needing to l2p here) that Aran can go to a handbasket pretty easy if there's a hiccup in the scripted event. Tonight our warrior resisted poly, and immediately triggered pyro. Practically back to back pyros are cool. Next attempt (would've been last of the night thanks to the respawns), something else happened (it's like he desynched for a second, and then became the Kwisatz Haderach, the man who could be in many places at once.

Lacking any convenient deserts to exile him into, things didn't go well for our side.

I don't mind that it happens. In fact, meeting the Maud'dib was pretty cool. But such chance encounters (read: heavily scripted and thus prone to random bugs until the end of time) being tied to timesinks... no thanks.

There's another trick than just going out of LOS?

You idea if ideal is awkward to me. Ideal situation would be that you spend most of the time learning new encounters and have to farm old ones only at most few times or so, preferably even less. This is ofc not possible due to cosntruct of instances which force you to farm the first bosses multiple times nor due to low droprates of items.

Rogues can stun them or something, just at the last moment, and they won't do their explosion. We rarely have them explode now, which speeds things up considerably.

Fear seems to work as well, the priest variant since the warlock seems to break a second after applied for us.

It's got a very, very short cast time (like .5 seconds), but they're stunnable. So have the Rogues/Druids/Paladins keep Kidney Shot/Bash/HoJ at ready.

I'm quite sure the explosion happens regardless.

Guess I'll just tell our rogues to practise more then, haven't been able to get them stunned with any certainty up to now. Tanking them in the doorway so you can dodge out of LOS was easier at least for us.

And going back to the topic: hate the post-Curator trash too. Just hoping they'll thin it out some at some point.

You can stop the explosion by bursting them before they have time to cast (only done this once), or by our method of fearing/chain-fearing them around 4-7%... they grow big and... just die.

Deathcoil works here

Trash is what I really dislike about Karazhan. The whole zone is done so well, but when you have to re clear trash all the time because of a wipe it gets frustrating. I hear Serpentine Cavern has the same problems with a 45min trash timer on Hydross. Personally I would love to see trash only respawn on a soft reset of any zone until you kill the boss that controls the respawn. There is so much raid content that people can do right now why try and limit us?
