Could be because Zantai wants a better environment to guage SR performance of builds.
Right now, unless the authors state whether something was done with Camera trick or pulling one-by-one without it (possible if Lava map), or if the build can take on all 4 at the same time, the devs have no way of knowing unless they play the builds themselves to test or make the praetorians do it for them.
One gripe people have had in the past, or atleast myself personally had voiced was how balancing tends to be done solely (or mainly) based on Crucible performance. Many consider it to be a better testing ground since there is not as much randomness to it.
But where Crucible favours speed, SR needs much more survivability and you can’t have complete glass cannons give the same performance there. Nerfing builds based on Crucible however, nerfs them everywhere, including in SR, which I personally had also complained in the past to Zantai and I am sure I am not the only one.
But if SR could be made easier to balance around, it could be taken as a valid metric and can end up creating more variety among builds with some tuned for SR and balanced around it while others still speedrun Cruci.
But then comes the question, do you balance around aggro pulling / camera trick or without?
A build that can do SR 120 might hit a wall around SR 85 without camera trick or pulling one by one. And if the game mode was originally intended to be played without the trick and most players are not aware of it anyways, it makes sense to remove it altogether while providing something built-in as compensation.
Ofcourse, that alone won’t fix the inherent randomness of SR or suddenly make people flock to it. It also alienates those who believed the Camera thing to be fine or even the way to play SR. It creates unnecessary problems with the proposed change as currently you have the choice to aggro 1 by 1 or 1v2, or 1v3, or 1v4 at once, which once the change drops you will be forced to 1v2 for the last 2 bosses even if you don’t want to.
So, yes it is a mixed bag. No, it won’t solve all the issues with SR. Yes, there could be better ways to “fix” the issue. But I doubt Zantai is going to discard the change because of our concerns with no one having actually played or tried out the new patch. If it does end up creating problems, Z hopefully will make changes as needed to address them.
All this aside, personally I would have loved to see SR get its own unique monsters as Level bosses with just 1 boss in the boss room. Like that giant maggot, or the eye thing, or that Damage Sponge Aether construct which we all hate
Would have been easier to balance, most of the stuff needed including not just the bosses but also their unique maps are already ingame etc. Would also give them more spotlight since atm it is random whether you fight them or not and most people consider these special stages or atleast that Aether Construct one to be just a waste of time that might even warrant a Reset.
(I cannot kill it after a certain level for example even though the builds can easily kill Nemesis bosses 1v1 in the boss shards of the same level)
