Occasionally, I've encountered opponents with the "Jailer" affix, and some bosses seem to have attacks that hold you still (though you aren't frozen). I've discovered the Wizard's Mirror Image, if cast while rooted or frozen, will allow you to escape sometimes, and a message will pop up that says "Broke Root!" or "Broke Freeze!"
This can often be the difference between life and death, so - what other abilities (for any class) allow you to break root?
Monk: Serenity
You are enveloped in a protective shield that absorbs all incoming damage for 3 seconds and grants immunity to all control impairing effects (4 seconds with Ascension rune).
Witch Doctor: Spirit Walk
Leave your physical body and enter the spirit realm for 2 seconds. While in the spirit realm, your movement is unhindered.
Your link to the spirit realm will end if your physical body sustains 50% of your maximum Life in damage.
Demon Hunter: Smokescreen
Vanish behind a wall of smoke, becoming momentarily invisible for 1 second (without Lingering Fog rune, 1.5 with).
Wizard: Mirror Image
Summon 2 illusionary duplicates of yourself that last for 7 seconds and have 25% of your Life. The images may cast some of the same spells as you, but those spells deal no damage.
Wizard: Teleport with Fracture
Normally you can teleport when you are Jailed, but you will still be jailed after Teleporting. With the Fracture rune the Teleport will function like using Mirror Images, breaking the jail. Teleport will not however work while Frozen, like Mirror Images will,b ecause for the Images to spawn you need to Teleport first.
Barbarian: Furious Charge
Rush forward knocking back enemies and inflicting 195% weapon damage to enemies along the path of the charge.
Barbarian: Wrath of the Berserker
Enter a berserker rage which raises several attributes for 15 seconds.
And related to using abilites while supressed, the Wizard can activate Diamond Skin even under CC.
The Witch Doctor has Spirit Walk. I've only used it to break freeze, though.
Demon Hunter has Smoke Screen, allowing to vanish behind a wall of smoke, becoming momentarily invisible. It works very well for escaping most enemy traps.
Specifically for the Jailed effect, the Monk's Dashing Strike ability allows you to move a short distance while within the jail.
You're still stuck in the jail, though.
Aside from the skills listed above, there are the Legendary Boots called Ice Climbers that allow you to completely ignore all freeze and immobilizing effects. They're a good alternative if you don't want to use a skill slot for this effect.
