What I'd like to see are things like Ruin III replacing Ruin I during Dreadwyrm Trance, or Fire IV/Blizzard IV replacing Fire III and Blizzard III respectively while Enochian is up.
I'd *love* to free up some keybinds. Controller space is also at a premium here, as they don't just use those bars for abilities, and I don't/can't use an MMO mouse so I'm pretty much limited to 10 buttons I can comfortably hit without drastically altering my keybindings.
As it is, I click CDs when I DPS.
