While you surely you could though Karazhan, Gruul's Lair, SSC and Tempest Keep without having abilities like Improved Shadowform, they become extremly viable and important for Black Temple and Sunwell Plateau.
If you read the discussion about improved Vampiric Embrace, this apply to the same ruleset. It's no shame to respec according to your level of progress, and to your group setup.
A example for Holy is Spell Warding. Again something that is semi-useless (5 points, Holy Tier2) for Tier4/5 bosses, but almost a requirement to do Gurtogg Bloodboil (5th boss in Black Temple), and almost all bosses in Sunwell Plateau.
