We just hit HoT on Mischief and I was trying out combat dummies and noticed Clash of Many nor any other "of many" spells were showing up in my tabs or on parse regardless of how many pets I had on the target. I noticed it did trigger augment and bard procs. Is this because combat dummies don't have a hate list and therefore it registers as 0 pets? Any mages figure out a clever workaround to this? Kinda disappointing but oh well.
You can tell test server dummies in the arena to fight back which makes them behave as expected with -of Many nukes.
