It works on the PTR!
Balance: Still exactly the same.
Resto: As you know they changed the spell so you can only have one shroom that gets relocated when you cast the place mushroom thingy again.
Sadly they changed the bloom spell for resto to only trigger one shroom but since the cd is only 10 seconds and the duration of the totem is 15 its possible to get them both exploded.
They made the create shroom and bloom share a 3 second cooldown so you'd have to wait before you can explode the new mushroom.
Code:
/use Poison Extraction Totem
/cast Wild Mushroom: Bloom
With this you can instantly explode the totem without having to wait another 3 seconds.
