This is a thread about the animation snapshotting so my post was about that. I'm not commenting on how other changes might affect how a job plays since that's off topic.

The changes to snapshotting made it much more easy to extend dancer's stun from 2s to 4s. In 7.0 it was next to impossible.

It also changes it so that if you can get the stun out, you have a chance of escaping and surviving. In 7.0, by the time your animation lock ended, the enemy was no longer stunned and would burn you down instantly.

You still have to survive getting the stun off in the first place but that comes down to playing intelligently. Don't run directly at the enemy's face. Don't pop LB if you're being heavily targeted. Attack unseen from the flank or rear with a gap closer. In 7.0 you could apply these tactics and by the time the enemy notices you, their stun has worn off and they kill you. In 7.1, by the time they notice you, you stun them. Massive difference.
