We've seen in videos what some of the "get out of jail" utility powers are (wizards teleport, rogues dodge, etc.) I was wondering how this might visually look for druids or other primal classes and came up with a few thoughts. These would all propably require a reasonable cooldown
When pressing Shift, a mass of roots rips up from below the druid's feet and yanks him underground for 2 to 3 seconds. During that time he's effectively unassailable but cannot himself do anything until those few seconds have passed.
When you press shift, what was once a humanoid explodes into a cloud of insects (or maybe some other thematically appropriate swarm/cloud--sand for desert druids, for instance) that reconstitutes into your character a few seconds later right where you were sanding. The attack you "dodged" just goes harmlessly through the swarm.
Based on the way the wizard's teleport looks in the videos floating around (I'm assuming this would just be a variation on the same tech) it would be neat when you press Shift if the character's appearance poofs into some random small animal that scurries or flies a short distance away, then poofs back into your druid. It would be a very, very quick transformation though, considering how quick those wizard teleports look to be.
When you press shift your character becomes covered with a bark and his body twists into a roughly tree-like shape for a few seconds. Similar to Buried Undeground he remains unassailable and immobile during that time before turning back.
Just Takes It And Doesn't Care
Thinking about the barbarian and how the guardian fighter's utility appears to work it might be entertaining if a barbarian's utility had the character just stand defiantly and take a blow without breaking a sweat out of sheer tenacity.
