Long-term (ie: not for 5.4), we will be making some bigger changes to
the Hunter class. It may not be a full class revamp (like the Warlock
revamp in 5.0), but we do want to give the class a full once-over and
make sure that the specs feel different and unique. We are not planning
any further, class-wide mechanical changes for 5.4.
We have not yet balanced DPS for Hunters (or anyone) for 5.4. When we
do, we'll make sure that as much of that balancing as possible is done
via signature shots.
By that, I meant that signature shots are going to be the primary target
for any buffs to bring Hunter damage up, but there's only so much we
could buff them depending on how much actually needs to be done. We
wouldn't, say, allow Explosive Shot to tick for 500k just to bring
Survival PvE DPS up. Instead, we'd bring up Explosive Shot as much as we
comfortably could, and then make minor tweaks elsewhere if further
balancing was necessary.
