To all of those farming Amdapor Keep, I write this message to you:
Please, for your own sake and the sake of others -- please stop attempting to farm Amdapor Keep. Now wait a moment, before you rapidly try to chop my head off allow me to first explain why. Now, Pre-Patch, Amdapor Keep was quite easily farmed by teams which had some pretty decent damage output. Now, Post-Patch, only those with extremely high-end DPS, such as Relic and Relic+1, can successfully milk Amdapor for resources.
Yet, if you do not have your Relic. By all means, avoid this dungeon as though it were the plague. For it is only a massive waste of your time and effort. You will suffer a long, long wait to even reserve yourself a single instance with a full party. You will almost never see entry into it if you are solo-queued. Even if you get in, you will then have to slog through almost 30 minutes or more (without high-end DPS), of costly dungeon which nets you very little reward for the effort.
So you know, there are far better ways to farm for resources in late game -- especially Mythology. For if you are one of those who desires Mythology, you can earn far more by farming Primals. Furthermore, you will also gaining better weapons.
For instance, one can wait up to 25 Minutes for entry into Amdapor Keep. Then run probably 35 minutes in the dungeon itself, maybe even longer with errors. The run could last 40 minutes or at worst 60 if the team is not capable of handling the boss fights. This means you can waste up to 1 hour to 1.5 hours trying to merit yourself 40 Mythology.
In 1.5 hours you can perhaps run 9 - 11 Garuda Runs give or take a few minutes for mistakes and/or breaks. Each successful Garuda kill nets 7 Mythology and an extremely powerful weapon.
So in the time you've spent trying to get 40 Myth in Amdapor, you'd instead earn 63 - 77 Myth in Garuda.
Note, I speak of course of very effective and quick-to-kill Garuda matches which end fairly quickly. This takes skill, timing, and determined players who know their roles and perform them very well.
Seriously, the only reason there is a need to even enter Amdapor now is to just get past the point on your Relic. You will make far better returns doing other content to get your Darklight.
That is all.
