Coming soon™! Just about sums up Rift 4.0 so far wouldn't you say?
It's very obvious that SFP has been a rushed disaster from the start. If anyone will be around to play with when that eventual future awesomeness happens is another matter entirely.
As much as I would love for this to happen, doing so would only serve to reveal how shallow Rifts combat actually is. At the moment, it's obfusicated by the fact that without macroing you've got 200 abilities on your hotbar - And probably just as many off it that you'll never use sat in your spell book.
There's very little actual mechanical depth to the combat, a couple of procs here and there sure, but I can't think of even one case where my characters performance has hinged on my ability to use a certain mechanic. Maybe that's just because I was playing a Mage? I can't really say of other classes have anything that would fit, but I know for certain that Mages didn't. If anything, it's made me appreciate the design of the old Assassin Rogue in WoW TBC where you had to actively manage the Find Weakness buff. Keeping it active, along with Rupture and Slice n Dice, took lots of practice. If you wanted to squeeze the most DPS out of it, you had to understand that there were times when you could let the buff fall off and pool your Energy without losing DPS, and times when you could make that practice pay off by getting extra Envenoms off. Rift has nothing of the sort and hides that fact by giving you a vast quantity of abilities, with very little mechanical quality to them.
Resource bars are effectively meaningless too. I've never once ran out of Mana while playing a Mage and managing charge was only really an issue for playing Arbiter. To be honest, I've really been wondering why they're even there!
