It would be cool to see this feature return!

Sadly, this feature was deemed too difficult for modern MMO players to comprehend, and was thus removed with the transition from v1 to v2. Interesting as it was, I doubt we'll ever see it again. The same holds true with Battle Regimens, which were incredibly powerful when executed by a team with coordination.

Sadly this. SE have created this game to cater for the lowest common denominator so any core mechanic that would be too difficult for a 5 year old child to understand is automatically out of the running. It's the reason that ninja was nerfed after SE realised that players weren't completely braindead and could actually use it to its full potential.
