I've had the opportunity to raid since the patch but I will hold my final verdict for a few more days (or depending on how much I raid - weeks). I think we need to get some basic kinks out to see how this patch really affected things.
Patches always bring problems. I really don't have a problem with that. If it was a passenger on a plane, sure I wouldn't want the controls to be buggy. But this is a game, I'm willing to give some leeway as Blizzard gets the kinks out.
Yes, things have been bothersome. The interminable clicking sound caused by Blizzard's raid ui. The missing pet bars. Our guild has had trouble with bosses we've had on farm for a while. I don't know whether to chalk that up to the mods in general, or the changes to decursive. My guild has been gracious enough not to lay blame at any particular class or group - we're all adjusting to the changes.
Normally I'd be more upset with what I consider to be a detriment to support classes. But I'm growing more apathetic with each raid.
