DS end game has been a lot less fun for a while. Both of my raids are now losing people - 1 due to work (and that raid is already short a reliable healer), and a tank/dps who wants to avoid burnout (although we do have a healer who has a tank, but then we need a healer).
DS is also much shorter than ICC - 4 less bosses and a lot less trash.
When the ship lifts, all bills are paid. No regrets.
