A good alternative to saving stats, tho stat saving is preferable, would be to make re-assigning stats take stats all the way down to base, returning all points at once.
Re-assignment should be allowed more often than the current 1-hr. Maybe 30 Minutes or less. (preferably 0hrs 0mins 0secs)
When adding points to stats, instead of having to make multiple clicks to ad a stat past 40 points (adding 2+ points to equal 1 attribute point increase), instead, make the click take all the points required to add 1, making it take much less clicks to add stats back after re-assigning. pushing the button 4 times to make 1 attribute point is annoying and time consuming, and makes my mouse unhappy.
It currently takes forever and a day to reassign stats in order to play a different class effectively. I know there are plans for stat saving at some point in the future, but this will also help a lot and may be easier to implement.
