I can’t speak for the other shrines yet, but the conduit shrine is still not powerful enough even after the mid-season patch. I’m playing a LS sorceress and I got a conduit shrine with attack waves. I only managed to kill 2 waves in the time that the conduit effect was accurate and then once it wore off, I killed off 8 waves. This was in T4. An effect should buff a character, not nerf it, and this is what conduit did for me. I’m going to start avoiding conduit shrines again until this is properly fixed.
