I was in a farm raid for Trees in Naz and I encountered this Sin rogue who was doing a lot more damage than their poor gear choices should have allowed. When I checked on Details, their lead spell was Tidal Storm (Tidal Storm Link.
Now this isn't the same as the Tidal Storm from Shaman abilities, it's a different Icon, the spell I linked is the correct one.
This was their lead spell with I believe Rupture being number 2. Their gear wasn't really fantastic, I think they had 1x Shroud, 1x Engy ability, Undulating Tides,... and they were pulling around 24k dps.
But Tidal Storm was doing a huge amount of that damage, and I'm curious as to what is causing it, if anyone has run into it. I don't think it's Undulating Tides, because the tooltip for Tidal Storm doesn't match what UT does. They were also using Lucid Dreams for Maj Azerite.
The only thing I could think is it may be related to the healer follower which I haven't used yet. Regardless does anyone know what is doing this, and why it's doing so much damage.
