Blizzard replied with some comments about how the Diablo 3 bosses Waller affix. The original player post is very long and thus not quoted below, but the OP quotes a lot of others complaining that Waller walls sometimes appear right on top of them, or that multiple walls from Champions block them from moving, generally right when an Arcane needle is turning their way. Blues made a couple of replies, which are quoted below:
If you’re still running into situations where Waller monsters are spawning their walls right on top of your characters, we would really appreciate a list of steps that you took to get this bug to occur or a video that shows when and where this happens. (While we’re super thankful for the reports and screenshots you’ve submitted thus far, we just need some additional details to figure out what’s going on.)
For clarity: Waller champions will sometimes spawn multiple walls in a tight formation near a player, which can limit mobility. This is not a bug. However, if a single Waller wall is spawned right on top of a character, causing it to be unable to move, then that’s a bug and we would like to know more about these situations.
This doesn’t make any sense to me, what’s the difference if you’re stuck between multiple walls or just stuck in one wall.
Lylirra: In one situation, you have monsters with the Waller affix spawning walls near a character in a tight formation, or adjacent to one another in a way that may limit where your character can go. This is not a bug.
In the other, you have walls being spawned directly on top of a character, which basically makes it unable to move in any direction until it despawns — and this is regardless of where the other walls may have spawned, too. This is a bug, because walls should not spawn on top of characters.
We made some changes in patch 1.0.7 which we believe should have fixed this, but since we’re still getting reports from players, we’re continuing to investigate. Right now, we’re having trouble replicating the bug on our end, so we’re reaching out to players for more information. The more information we have, the better our chances to replicate the issue. Replicating the issue internally is key, because that let’s us know what the problem is and, in turn, how to fix it (ideally).
Also, I feel it’s worth noting that, while it’s currently the intended behavior for monsters with the Waller affix to be able to spawn tightly near a character, that doesn’t mean the functionality is set in stone forever. We’ve seen a lot of great feedback from players on the affix (like giving walls HP or purposefully staggering where the walls spawn) that we’re definitely reviewing.
For the purpose of troubleshooting, though, it’s important for us to identify how the affix is supposed to work right now — what behavior is intended vs. what isn’t — and make that distinction as clear as possible for you. Even if you disagree with how the affix is designed, we still want to be able to fix the bug, and understanding what you’re experiencing (normal mechanics vs. bug) is a key part of that.
A lot of the player comments in the thread are easy to dismiss, as people genuinely seem to think that no Boss Affixes should ever be dangerous, and thus Waller should be nerfed or removed since it might actually cause someone to get killed. (Hint: that’s the whole point in boss modifiers.) That said, Waller isn’t meant to be an unbreakable version of Jailer, so a single wall shouldn’t stick you like a butterfly on a pin.
In my experience, when I’ve been “stuck” by a single wall it’s always when I was moving very quickly, either via something like Tempest Rush, or more often some sort of a teleporting skill. The game tries to put the wall at least a few yards from a character, but if the character is really zooming, you can get right on top of the wall when it appears.
That said, I’ve never actually been stuck by a wall, and there’s always one direction go move that will get me out. The tricky part is that it’s not always the obvious direction. I’ve been right on top of walls that look 1% to my left and 99% to my right, but when I try to go left I can’t move. However, if I spin the mouse around and try to move in every direction, one way will take me free. IMHO people who die saying they were “stuck” on a single wall didn’t try moving in every direction, either because they died before they had a chance, or because they panicked and only tried to move in the direction that appeared to be open.
You are, of course, free to disagree in comments.
On a more general issue; are you guys satisfied with the current Boss Affixes? I am not, and I keep hoping Blizzard will add some new ones, or tweak some of the current ones. I want more variety, and more danger, or at least affixes that force me to alter/vary my play style more often. For a skilled player with good gear, the only real dangers are spending too much time in Arcane Enchanted beams or eating more than 2 Molten explosions at once. Other mods can tie into those, especially the CC ones like Frozen or Waller or Vortex or Nightmare, but all the rest are basically irrelevant, in terms of changing my play behavior.
