Dunno what synergy bugginess are you (and several others I saw) talking about. Complaints about synergy was all around the place since Homestead. I personally created at least 1-2 threads about it. Now either I got too used to it or something was maybe even improved, but I didn't feel any problems with synergy since latest patch. More than that I felt like it's coming easier than before. Maybe it's some specific synergy you have felt difficulty with, like Healing Orbs. But they were buggy long long ago. They are not even worth slotting because too distracting. Mystic orbs have better synergy it feels.

The problem with Torugs is that although it looks fairly good in theorycrafting if you go with less than SUPER optimized group you will get your infused crusher stolen by others. I still run infused crusher on my heal for example, simply because it's really rare to meet tanks wearing Torugs. So your set up is only good for a group of players that you know very well to the point where you are sure none of them have crusher enchant to steal your Torugs crusher. This is how I see it.
