Hi. I have been using several dmo builds and have had it not cast slow time repeatedly and it is making the builds completely useless. This appears to happen mostly on larger mobs and those that are immune to CC or damage. It has happened on regular groups of mobs as well.
Builds: MM (Glacial Spike) Fragment of Destiny (Sanct) + Mirrorball and Energy Twister+Arcane Torrent
Energy twister will correct itself if I hit the mob with arcane torrent.
