There's no need to reroll a 28 point character. as MANY people who have both 28 and 32 point chars have noted, the 28 point chars are by no means gimped. If you're obsessed about the fact that there's a theoretical possibility that your character could have slightly higher stats, when this fact has no reflection whatsoever on your ability to complete dungeons and contribute to a team, well, you're going to hate a lot of things about this game.

The advantage of a 32 pt character over a 28 pt character is very small compared to the advantage of a twinked lowbie character over a non-twinked lowbie character. That rogue you're running with in waterworks, who's got the fancy gear has a much bigger advantage over you than does a non-twinked 32 pt character. Does that mean that the really good gear should also be for sale?

And at higher levels, shrould items really make a much bigger difference than 4 build points. SHould shroud gear also be for sale (it's much more of a grind even prepping for the shroud, let alone getting the gear than it is to get to 1750.)

And the complicated builds taht are supposedly so sensitive to the 28/32 difference? They're also very sensitive to gear and tomes.
