[caption id="attachment_385773" align="alignright" width="202"] Not just a Hardcore excuse anymore.[/caption]Since Patch 2.3 went live we've seen constant reports from players who can not party with a pet-using Witch Doctor since the lag is immediately overwhelming. (The WDs themselves don't seem to be affected, especially not playing solo.) While the problem is worst with WDs, it's not *just* WDs and various combinations of skills/gear/LGems are making the game unplayable for many fans. Blizzard Investigating Crippling Multiplayer Lag: Jaetch: Lag on nearly every single cluster of mobs we encounter. DoomBringer: We were in a party of 3 --- 2 Helltooth WD and 1 DH. Every time there was a medium size pack, the game would lag. Against a huge pack, I could probably take a nap before the game goes back to normal with either all of us dead or all enemies dead. LudoBN: Every group with at least a HT WD is laggy Every group with supp monk + EP monk is laggy Every group with 2 delrasha sorc is laggy Every group with more than 2 Hota barb is laggy Every group with more than 2 WW barb in same area is laggy Group with 1 supp monk + 1 supp barb + 2 hota barb or 2 dart WD are quite ok (Some lag but "reasonable") Kobrakai: Every time there's more than 15 monsters on the screen the whole game stops for 3-4 seconds and then everybody is dead. We actually left a game on a great map with great density after only a couple of minutes because it was unplayable. Boozor: It is not just WD's, HOTA barbs using pain enhancer have the same effect. Even just 1 pain enhancer will lag the game out. Tyvalir: As you may have heard last week, finding the combinations of skills and situations that cause lag is an ongoing process that requires us to be very thorough. The more details we have, the faster we can drill down to what's causing it, so this is great info to have. For those adding their reports to the above, if you could share what skills were being used when the lag occurred, whether you were on a particular map or facing a particular enemy, and any other details you're able to include, that would help. I'll go ahead and forward this thread. Many thanks, everyone! Edit: Also wanted to link to John Yang's comments about the Helltooth Set specifically. In short, we've fixed some problems with it, and we're continuing to optimize it.[source]http://us.battle.net/d3/en/forum/topic/18706416749?page=2#39[/source] The OP, top Wizard player and B.net MVP Jaetch, offered up a video showing the sort of slow motion lag players are complaining about ruining their efforts in a GR75. Click through for that visual accompaniment. Talking to some players lately, I've heard a lot of complaints that while Patch 2.3 was brilliant on content, it's the most bug-filled patch yet in Diablo 3 or Reaper of Souls. I guess it's not a real surprise that there are some new issues, given the nearly infinite combination of special properties Kanai's Cube has created, but it's unfortunate that this sort of thing is ruining the great content of the new patch and season, for so many players.
