AE Root

[Jackpine]

Hail all!

I am a 59 druid about 3 yellows from 60. (close but not really) I bought the level 60 ae root spell and was just wondering if it is as good as it sounds? I picture using it to lock down a room on the initial pull then single target rooting once under control. It kinda seems like it's too good to be true. Also what is the duration of this ae root? If it is 3 mins like the single target one that seems way op. I think the wiki says 3 mins but it's not always accurate. Just trying to look ahead a bit and get some ideas, any input is appreciated. Thank you!
