The waits for running CT (Labrynth of Ancients) are horrid on pretty much any class, since people only have a reason to run it the one time every week. Why not add a Sands of Time to the end to give people a bit of incentive to run it more than once... the Allegan Catalyst is a garbage mat, and the Sands of Time is to upgrade gear that's already halfway obsolete to being up from i100 to i110, when WoD drops i120 so adding an extra to CT is hardly gamebreaking... plus the two Sands at the end of ST are hardly enough to satisfy the needs of players to update the variety of i100 gear still spread across all the classes a lot of players use, as evidenced by the fact that unlike the UAT, no one ever passes them.
