Graveyards
I apologize if this topic has already been made in this forum before. The search function isn't the best.
A lot of people are irritated by the difficulty of graveyards, and I can understand why. Yes, I know they are where "Even monsters fear to tread," but I find them as difficult as the optional area levels, but without the optional.
Personally, I love the look and feel of the graveyards, and I really enjoy them. That is, until the Phantoms show up. These guys need to be nerfed quite a bit. There are 4 ways I think this can be accomplished:
1) Just remove them. Not ideal, but I wouldn't complain.
2) Increase the re spawn counter by at lease triple. They come back too soon, especially when dealing with a hoard of zombies.
3) Reduce HP. If we could take them down quicker and move on to other targets, we could move to a new area before they re spawn and have to kill them all over again.
4) And my personal favorite. Make them killable. Once you kill them, they (drop loot!) stay down until you hit a checkpoint, or more spawn in a predetermined location.
Hopefully you at 3 Rings will consider this, as it seems a large portion of the player base feels the same way.
Thanks for reading this!
So much hate for such an easy level lately. I'll say it again:
Alchemer(or hell, a Blaster would work) + Kiting = toothless phantoms.
If you find yourself in a random group, Just tell them to kill off the zombies FIRST; THEN come help you with killing off the phantoms. As long as they don't chase after the phantoms while you're kiting them, they shouldn't get any aggro.
If someone refuses to listen, just kick them out and be done with it before they get himself killed and starts being a little baby man.

As Magnus said: Don't fight them at the same time as you're clearing through a mess of zombies.
Additional tips on that issue:
1. Don't run away/retreat/lure phantoms to unexplored areas. When kiting stay in already explored area to avoid unexpected zombies.
2. If you encounter new area full of tombstones and it is long time since your last phantom fight, wait for respawn and kill him again in some already explored area before going into new area - that way he won't interrupt you in the middle of zombie battle.
Also note that although tombstones won't block phantome itself, they are still blocking projectile from his charged attack - it may be wise to fight him not in corridors but rather amongst the tombstones.
From reading the forums, phantoms have already been nerfed. You might want to invest in an avenger as well.
Though the spawn rate should probably be changed. I don't know, when I was in a party of 3, we "killed" the phantoms and they respawned before we could even get out of the little room we killed them in. I understand that they're meant to be what makes graveyards difficult, but I'd like a little bit of a breather before having to fight them again.
Maybe make them respawn a bit slower - but with an Avenger or Fire Brandish they're pretty harmless. Even with a Vile Striker it's a game of get a few hits in, and hold your block. When they're charging, wait for them to release, then move to the side.

Although I have no problems with the current phantoms perhaps with multiple phantoms the respawn timer should only start when all the phantoms have been killed? Just a thought seeing as most people are complaining that when there is a party its too hard and when you are solo its very easy.
Protip: Don't fight them at the same time as you're clearing through a mess of zombies.
Also, enemies get more health when there are more players.
