There will be changes to this through the on-going balance project. While we are focussing on the PvP side at the moment - based on what we hear/see in the community - the initial set of changes will make a difference to levelling. Once we have a stable foundation for PvP there is still a ton of work to do for game balance and PvE is part of that.
Plus, the whole new player/character experience needs a significant overhaul. We don't deny that simple fact but there are only a few of us and there is a breathtaking amount of work to do.
