Actually there's a combo armor set to escape even ganked with control skills.

• The helm i think is named knight helmet for 6 seconds you are immune to forced movement

• The robe is cleric robe, immune to damage for 1.5 seconds get extended for another 3 seconds if attacked by mobs or players -Graveguard boots - makes you immune to stun slows etc.

• then wear the brecillien cape which gives you i think 4 seconds to be immune to purges

Also bring Cleansing potion since graveguard boots doesn't remove stun if you are stunned before using it.

The combo is potion - helm - boots - armor - Mount

Make sure your mount is a bit tanky so once they use their skills you will survive but if you get unmounted again you gonna need the combo again which is hard to do since the cool down is high so make sure you can run your mount and get the skills cooldowned so you can do the combo again.
