What a cool ability!
Remove your group from combat, invis, IVU, HP regen and mana regen!
...But it's a 5 second cast as an emergency button with a 30 minute reuse. About as useful as an airbag you have to self inflate right before an accident.
I have been testing the ability both solo and with groups and it's totally unusable in an emergency when you are under attack - you cannot get a FIVE second cast spell off while being beaten by anything, especially 50+ when the mobs become very powerful.
You cant really save a party member in deep trouble either due to range and cast time. When you're puller gets too many you can't save them.
The ability ends up just being a 30 min cooldown that gives you and your party a little mana that you have to dedicate a spell gem to ALL the time.
### REMOVE the cast time, or drop it to1 second tops
Ritual of Escape is supposed to be the Shaman's answer to rez and ports. It doesn't come close as a desirable ability and you get it alllllll the way at level 40, meaning you've dumped well over 100 hours into the class before getting it's supposedly defining ability.
