2. Life Tap is not as much of a dps loss, due to the less time spent in GCD. This isn't as big as number 1, though, because if you still focus on LT only while moving, you don't spend as much time twiddling your thumbs while Life Tapping.
3. Not so great for the Warlock specifically, but not having to keep the 40 (or is it 45? haven't played the Lock in awhile) second SP buff up at all times is very useful for the healers in your raid. If mana conservation is the key for healers in this expansion, they clearly don't need Warlocks going through 3 full lifebars during one boss fight just to keep a sp buff up. This also means Locks don't have to focus on Drain Life as much (as it seems GC wants them to do) because you're not Life Tapping all the time.
Keep in mind with the new system for glyphs, you're not as restricted in raids anymore. A good example would be something like glyphing for a lower CD on Teleport for movement heavy fights, then changing that to Life Tap for Tank 'N Spanks. Just a quick thought.
