Mass Effect 2: Change Class on Import?

Mass Effect 2 lead system designer Christina Norman has once again stopped by the game's official forums, and this time she'd like some feedback on whether or not players would like to switch classes when importing their version of Commander Shepard from the first game.
Another question for you guys, how would you feel if on importing your ME1 character into ME2 you were given the option to change their class?

Suggested reply options:
- I would use this feature
- I would not use this feature, but I don't mind if it's available
- I don't want this feature to be available to anyone

When giving your reply option, please feel free to tersely explain your choice, but just replying with one of the above is helpful.

Why would we want to do this? Here's a theoretical situation. Joe has finished ME1 with a Soldier. After playing through ME2 which his character, he really wants to play a Vanguard, but he also wants to make sure he can make meaningful choices in ME1 that reflect the personality he wants for his Vanguard Shepard. He really wants to make basically the same choices he made for his Soldier, but now he feels like he has to go back to ME1 and do a full playthrough not for the fun of it, but just so he can get a properly prepared save game to bring over to ME2 with the choices he wants.

So the idea is, if Joe can import his soldier, and then choose to re-train as a vanguard, we can let him more easily do what he wants to do (play ME2 with the right background of choices without needing to do a full playthrough of ME1).
