I personally didn't enjoy doing ICC four times each week (twice on main, twice on alt), I feel like doing them once on each character is enough. 10m hard modes were just a much much simpler version of 25m hard modes that award the same loot as 25m normal, and since the gear dropped was different and usually there were 1-2 BiS pieces from those (such as trinkets), you were pretty much forced to run it (along with the fact that 10m hard mode progress was tracked by WoWprogress, and you want to rank high, so you want to progress through it).
To me, it just made current content more stale by running the same thing over and over again.
