Because they define the identity of the class differently than you do. ...and this Warlock main thinks that both Void and Solar are vastly better than they were this time last year. What has changed is that Bungie doesn't give you powerful builds out of the box anymore. You have to build them yourself...but the pieces are there if you set yourself to constructing a powerful build. The build I'm currently running is arguably overpowered for PVE play....and I still have room to refine it even more.
