Personally... I think there were two reasons behind the changed to resolve.
1. For all the reasons the devs have posted about with the effect being that its easier for solo que'ers not to white bar ppl as fast since those teams are disorganized for the most part.
2. its a secret nerf to melee classes that have been complained about for months because a lot of more casual players have not adapted to how to counter those classes. Now they can have more control over them because its much easier to stun lock them and shut them down.... even for a group of pugs with recruit gear.
I think you all got the nerf to marauders/sents you've been wanting... however indirectly.
I'd have to agree, sadly.
