I've been playing POE for years, and I can honestly say that this is by far the worst league mechanic I've ever played. I mean, I hated Sanctum, but at least I could skip it, and I fully understood the appeal to a certain section of the playerbase. But Necropolis is just awful in every possible way.
- The mechanic is forced, which makes me hate it right from the start. What makes this even worse is that GGG purposefully withheld this fact before the league launched.
- The increase in difficulty (which, again, is forced) is way too high and the rewards are practically non-existent
- The crafting is just terrible. Even if you got the exact corpse modifiers you wanted, the chance of you getting anything good is really really low. Even crafting with Rog has a much higher chance of giving you a good item.
It's really not that difficult to fix it. I can even get on board with the difficulty, but it needs to be much more rewarding. And you need to be able to skip the league mechanic. You do this and the league is fine; the people who can handle the difficulty can get good rewards, and the people who can't handle it can opt out.
Why are you being so stubborn GGG? Pretty much every other league mechanic has been optional; just make this one optional too!
