Star Wars Galaxies: Combat Balance - all at once or in little pieces?

Thunderheart shared his thoughts as he and the devs discuss whether they will bring out the combat balance bit by bit or all at once, and the possibility of a "sand box" being used to allow players to test upcoming changes:

I definitely think that one of the most important big changes is the Combat Balance. Things like the items you've listed here are definitely what would be covered in the CB and are critical. In the past few days, we've been talking about different ways we can break it out and accomplish our goals as fast as possible.

The thing about the combat balance is that it covers so many of these types of issues. As individual elements, they aren't so large, but in the scope of the combat picture in the game there are a lot of little pieces. If the CB is implemented all at once, it will seem like a gameplay change. If we do it in pieces, it will seem like a series of nerfs.

Im pushing and hoping for a more creative solution where we can create a sandbox for players to try out the combat changes and push them out in one fell swoop.
