The most recent change to Perplexity runes made it so the 6th piece bonus will only apply to the first target you interrupt every 8 seconds. This ruins any utility they had in group fights, since you can only apply confusion to a single target. This is a shame since they made Glamour Mesmers ALMOST viable in groups again.
The ICD should be bound to the person who the confusion was applied to, not the person using the runes. They should function the same way Frost Armor works, in that it will apply chill to anyone who hits you, but will not more than once per second for any given person.
