I have noticed virtually no change in the number of people leaving WZ's.
This 'fix' didn't fix anything.
FP queues have gotten longer.
People are still bailing on WZ's left and right.
The impact of this change has been an overall negative one.
This was the wrong way to address the issue.
A change was made.
It did not fix the issue.
It did more harm then good.
Several suggestions have been made on ways to address the issue in a much more acceptable way for all those involved.
Devs here's a perfect opportunity for you to react positively to the player base's request. We understand knee-jerk reactions are made from time to time without the full consequences thought out. Your "solution" has actually decreased the enjoyment/playability of this game. It's not too late to revert this change.
A little bit of effort can go a long ways of restoring the player's faith (what's left of it anyways) in BW/EA.
