With a mere 156 charisma, I've found this spell just lasts all day long. This weekend I used beguile a lot, leveled up to 39, and used this one a whole lot more. In dozens of charms, I had one instant break and one or two resists; every other time it lasted the length of the fight, and I was able to break it at my leisure with invis. In certain instances this is better than mez for group crowd control
And that is with the lvl 39 charm.
We need charm to work like it was in classic. I have never had a full duration on charm since the patch, even on green lvl 1-5's. (Some even broke within 1-2 minutes which is ridiculous)
On a scale from 1 to 10,
Charm before patch was a 10
After patch is a 1
Classic - 5
