Like I said, phasing has minor issues, but it's much better than what SWTOR offers. I find it sadly ironic that a game that isn't story-driven has more varied quest types and has a more dynamic world than a heavily story focused game. Bioware, the "experts" in video game storytelling, should have understood that a story is far more effective if the gameworld reflects the story.
Phasing is a viable solution to let players see the consequences of their actions even if it is limited. Also, WoW has been using this type of thing for four years, which is when Wrath launched. I didn't say that every single quest from 1-80 had phasing.
The overall point of my post was that even casual themepark MMO's can have permanent change. The technology exists. It's a proven concept. Sadly, SWTOR will continue to make every quest a, "Go kill/collect 10 animal parts" quest that will have ZERO impact on the gameworld and very little impact on the overall story.
