Shaman: Pact of Wurt

I've noticed Pact of Wurt chance to summon dogs is literally like 1%.... With the 35 minutes its active, I cast maybe 2 - 5 dogs. Pact of Alma is like a 30% chance and I'm constantly calling dogs...

Is this new? Did they revamp Pact of Wurt?
My shaman is 98 and using Alma because Wurt has become useless. Will we get a better dog summon proc spell?

Bold emphasis mine.

Pack of Aina only has a maximum spell level limit, which you fall under. Pack of Wurt requires that the spells you cast to trigger it be between 80 and 90. As you are 98 already, you are likely not casting any nukes or DoTs in that range, so no, it won't trigger. If you get Pack of Hilnaah, you'll likely trigger it off some spells, but honestly, since you're only two levels off 100, it's probably easier just to use Aina until you hit 100 and then get Pack of Kriegas, which has a spell limitation range of 90-100.

Not much longer and you'll get the 105 version which seems to proc very often, even more so when using the combination spells.
