I agree with you both, the PA changes were only made with DPS classes in mind, not with support/vit characters, this is the wrong way of looking at it because only a certain part of the players can now play PA properly (just like before).
One of the ways to change this would be to develop an assist system in which, when support characters party with DPS characters and help the DPS, they gain points based on their ''assists''.
This would 1: force people to party up and help eachother and 2. give everyone a more or less equal chance for points.
