Hi there! Before I begin, a few things. I already opened a thread on reddit, but I think it can't hurt to increase visibility by opening a separate one on this forum. So if you read both, please take into consideration that my arguments are largely the same.
For context: I am an average to a bit above average player with a lot of game time, generally only access to LFG for group content and over 37k Achievement Points. Those facts are important when talking about difficulty or about the sample size of similar content I went through.
This achievement is granted by getting through the Maze event on the Siren's Reef fractal on Master Tier (T4) without anyone in the group activating an orb. Sounds easy, but there are a few catches than on their own might not even sound too bad, but in combination result in a tedious and frustrating experience with an admittedly meager reward of 5 AP.
The Issues (in my eyes) are the following:
If one fails, everyone fails.
This is in general not a bad thing, but after checking a good chunk of fractal achievements I found out that every time this structure was used, it was either a trivial achievement, or one that gives you a strong reward. This is neither. In fact, even though avoiding fights is generally desirable, the maze takes too long so no group ever cares enough. This goes so far that people will actively run into the first orb they see to disqualify the entire group, no matter what you discussed beforehand. One guy can ruin the achievement for everyone even if they agreed to go for it, and this is the antithesis of fun; it creates hostility.
My suggestion is that the achievement should be tied to the individual, not the group. It might allow for people to get it via leeching off, but you can more easily kick those players if wanted and it completely disables griefing.
The Maze comes after a boss fight.
Again, in general not an issue, but if your focus is the achievement, this structure means a long and unskippable wind-up that, depending on your instabilities, might even get difficult to get through, especially with the small pool of people even wanting to attempt it. If you fail, you can't reset the achievement either. You have to leave the fractal and redo everything.
My suggestion is to implement a mote that resets the maze and achievement at the entrance. This way you still have to clear the first boss fight, but then are free to focus on the achievement.
The Master Tier.
I get why it is labelled as such, in every recent fractal there has been a dedicated Master Tier achievement. But, no other achievement has been influenced as much by instabilities. For a skill-based challenge, having something out of your control dictate not only the difficulty, but in some cases whether you should even try because it synergises badly, can't be intentional. Examples for bad instabilities are, among others: Flux Bomb, Hamstrung, Mists Convergence, Social Awkwardness, Birds (no longer ingame), and potentially Sugar Rush as I'm not sure whether or not the orbs get sped up. In addition, which is also unusual for Master Tier challenges, the Maze's difficulty does not scale with the Tier. The amount of orbs seems to be the same, and how many spirits spawn from one is irrelevant to the achievement.
My suggestion is to allow the achievement to be done on any tier, but I can see why this won't happen, as I wrote above.
In Conclusion, these three issues combined make something that sounds interesting or maybe even easy on paper in reality tedious, difficult, and basically no one even tries. That is obviously bad. Yes, it's only 5 AP, but achievements are content and should be looked at and, if needed, fixed. I've tried to assemble a group to attempt this every single day since the fractal launched, and had no luck. And I'll continue to do so. But I think much of the challenge is artificial, held up by decisions that we were told they wouldn't happen again (speaking of the long wind-up, if you remember the Living Story season 2, the Dragon Minion in the Grove for instance), and it is easy to correct. Also yes, on the surface, I'm asking for a nerf, but not because the challenge in itself is too hard - I'm asking for a way to make attempting it less tedious and annoying, especially if and when you fail at the first attempt.
As an aside, if someone wants to help me complete this achievement and is on EU, feel free to send me a message. Me completing it will not stop me from having this discussion, as I genuinely think that there is a problem that needs adressing, but it can't hurt either.
