Never seen an unexplained nerf

The PvP nerf to Elem and Enhance has yet to be explained.

I don't claim to study every classes issues so maybe this isn't that unique but I can't recall a time when a power was nerfed (in our case a power has been completely removed) without any discussion before of after the change.

I think it's astounding but maybe it isn't. Does this happen to other classes? I can't think of a time.


edit: obviously I'm referring to the nova totem nerf. it was possible to buff PvE without nerfing PvP.
