Galt just brought my attention to the artifact, and I follow up with this question:
once every 12 days for 500 credits vs once an hour for 1000?
For the purpose of allowing more frequent reincarnation for combat this is really lackluster, not just 'for the cost' but as a solution to the problem of statpack accessibility in general. I would gladly pay 500 credits to, say, automatically reincarnate into an intelligent lamira every time I become a Bard, but to pay any amount to be stuck in the same profession/statpack for 12 days is a chore more than a boon. The CD is too long. I'd rather pick up a profession in 12 hour increments via aspect than be stuck in a statpack that is not my primary for two weeks.
My friend has never played IRE. However, after a night of drinking and waking up early for work, he was able to describe his feelings perfectly by sighing, "I want to be shrubbed" out of literally nowhere.
