Being too dependant on damage during crusade is an issue.
Our mediocre dps outside of crusade is also an issue.
But those issues can both be fixed by nerfing crusade and buffing baseline damage. No ability reworking required.
I'd far rather see them remove the Retribution buff and adjust our damage to compensate. I'm sick of hoping to see a raid member die during crusade so I can do decent damage. And I'm sick of doing decent damage on the first pulls of progression, then as everyone earns learns the fight, performs better and die less, we move further and further down the meters. We must be the only class that gets worse as everyone else improves. It's awful game design.
