Right was doing some M+ yesterday.
In group with only guildies and all on discord.
So we sat and taunted each other about dam done, dam taken etc.
The I started mentioning each time my eye beam didnt occur.
First they didnt believe me, saying yeah you suck etc - all perfectly well banter in a guild group.
But after doing a complete dungeon - I came up with a number like 12 times.
I pop into demon form alright - looking like I do my eye beam. However there is no damage recorded for eye beam - and no visual effect either. Basically I look like the big bad wolf huffing and puffing at the 3rd little pigs brick house.
I had similar problem on my DH, when doing legion dungeons my character jumped, changed into demon and started to eyebeam. There should be few dmg values on the screen, but dmg started to count only when there was about 0.5 sec left on Eye Beam channel. So it’s like only 20% of proper dmg was done.
Edit: that was not lag, i have stable 27ms all the time and stable 60 fps too.
Sometimes I even did nothing at all, but auto attack - just to try eliminate stuff. And to show the guildies in the group, that I was not kidding. So literally standing 3-4 sec autoattacking - then EB - and sometimes nothing. Most times worked as intended.
I haven’t had this happen on my DH, but I did hear a DH in my group complaining about this. That said, I haven’t done much on the DH in a while, so this may be a recent bug.
I often have it stop halfway through and then start again usually when i’m trying to turn to get in more targets. I’m not a dh expert but it could be to do with range and width of the beam. In other words maybe you missed.
