Have you ever noticed about the bug along with playing patch 2.2.1 of diablo 3: the tornadoes aren’t moving very far from their spawn point, which can be a pain in some dungeon layouts. Blizzard has released the blue post to explain this bug. The details will be provided as below,and if you need to buy diablo 3 items, remember to check on our website.

There were no (intentional) changes to Rift Guardians in 2.2.1.However, there is a known issue with Saxtris and Sand Shaper specifically:

I had the same issue just now. I imagine it is a bug.

Nevalistis: This is correct. There is a bug with tornado behavior, and you’ll see this somewhat confused wandering with any Rift Guardian that summons tornadoes (Sand Shaper and Saxtris included). We’re currently investigating this issue.

To clarify, the tornadoes aren’t attempting to stay close to their summoner; they’re just changing directions too quickly. As a result, they won’t travel very far from their spawn point. The behavior of the enemies themselves should be unchanged so, in the meantime, kiting the Rift Guardian away from a cluster of tornadoes should yield more desirable results.

Not exactly the worst two Guardians there, at least not for their tornadoes. For more details and new information we will keep updating for you. And if you need diablo 3 items, our website will be a good choice for you. They will help a lot for playing the game.
