It would be nice to have first attemps locked to Practice.

A player should first Practice first phase 3 times (at least 30 minutes), then final phase 3 more times, after meeting this requirement, then they would be able to queue for Duty Completion.

Its annoying the amount of lower item level/unmelded players swarming the "Incomplete to Completion" queues, before even having touched practice.

A video won't make you understand all mechanics, you'll need to experience them first!
