In a game like WoW, new raid tiers come out all the time, and every time a new one is added, the old one becomes obsolete, which fuels a frantic race to get through the new content before it reaches the end of its shelf life.
In SWTOR, there's only a very small minority interested in seeing who'll be the first to get the kill of a new operations boss on a higher difficulty - plus as it stands, we've only had a single new operation in the last five years anyway, so it's not exactly as if there's been a lot to get excited about.
For most players, what matters is that ever since 4.0 Bioware has continually scaled all operations content upwards so that Eternity Vault from back in 2011 is still as relevant as endgame in 2019 as the more recently released Gods from the Machine.
This means that if you're not good enough to actually clear all the operations on all difficulties, you can basically keep progressing on them forever... which is exactly what my guild has been doing. The 5.x cycle has been particularly good for us because the boss's values remained stable for so long and we got access to some pretty overpowered gear pretty quickly. I got to tell quite a few tales of successful boss killing on this blog in the past year.
We still haven't killed everything though, and that's not even counting the most recent release, master mode Gods from the Machine. It's slightly awkward to think about, because if we're being honest with ourselves, it basically means that we're not very good. Some of these fights have been out for more than five years and we still haven't killed them? Come on!
A more charitable interpretation would be that we are very persistent and have taken our time getting better at the game. Most of us struggled with simple hard modes when they first came out, to the point that nightmare difficulty felt like something we'd be unlikely to ever reach in the future - yet here we are.
One boss I was really hoping to get down before 6.0 resets everything again was Dread Master Brontes on master mode, mostly because I have personal beef with her at this point. I vividly recall wiping to her in the run-up to 4.0, back when we were actually five levels higher than the boss and still found the fight too hard. I don't remember all the details, but I do recall thinking that I was sure that we were going to get her down before 4.0 hit because to me it felt like we were close. That didn't happen though.
August 2015
That was over four years ago now, and I really wanted to get her down this time. While we have to fight her at level now, we all got a lot better at the game in the meantime. And yet... this past Sunday was our last night attempting her as people voted to have a few weeks break before the expansion, something I can't exactly blame them for. I'm also not sure we would have been able to get her down even if we had tried for another three weeks, because unlike my fuzzy memories from 2015, it hasn't really felt to me like we've come even close to killing her this time around.
We are pretty good at making it to the last phase by now, but as soon as we're there it feels like everything falls apart in seconds, and the problem is that unlike with Revan for example, it's kind of hard to tell what exactly happened. There isn't a single mechanic that will kill you instantly, but there are a lot of things that can do a lot of damage, so it can be hard to tell what exactly killed any individual at a certain point, whether it was just too much unavoidable damage adding up and not enough healing, or whether someone or even multiple someones made a mistake that caused just too much extra damage at the wrong moment.
September 2019
There was a time when this sort of thing would have upset me a lot more than it does now (and I have the awkwardly ranty blog posts to prove it), but fortunately I have too many other things going on these days to get too hung up on a single boss kill. Plus we'll always get to try again after the expansion's release I guess.
From the way things look right now, there's even a chance that my prediction that things would become harder again in 6.0 might actually turn out to be wrong! I based this on the way things played out during the transition from 4.0 to 5.0, but as we know from the PTS now, Bioware is actually planning to scale us down to the old operations going forward, making Brontes (and us when we go to fight her) level 55 again instead of 75.
If scaling was perfect that probably wouldn't make much of a difference, but as it stands, downscaled high-level characters in SWTOR tend to be a bit on the overpowered side, and early PTS reports indicated that this effect applied in full force in the newly downscaled operations. So for all we know we might be able to waltz in there in 6.0 and one-shot her. It's unlikely, but... I'm happy to wait and see how things pan out.
