With Tso they introduced new AA called dimensional storage. What this does is suspends the pet and lets you have a back up pet for when one dies. But it can serve as a nice full heal to pet and remove and detrimental effects that may be on your pet. Cast time is 3 secs so you can use it inbetween nasty dot tick.It is instant cast for the pet to be resummoned. So for instance if in a raid and get hit with nasty dot that will kill your pet in 2 ticks<there>. Hit dimensional storage, then hit it again pet will be fully healed and cured of all detrimental effects in 3 secs...... fasters if have cast speed for abilitys.
