It"ll give an extra advantage to a few classes which is unfair in my opinion.Take an instance where a barb / Wr would change builds according to the opponents and people would QQ alot on that and for the rest of the classes it wouldn't matter at all cause they've got to stick to one build.That's the main reason why we stopped allowing people to go out and enter back ( changing | borrowing gear ,changing builds )..thats why the rule was implemented at first,which didnt allow anyone to go out once you were teleported.
An example of why this is actually probably a terrible idea:If you were allowed to restat between fights, I would switch to full Str and full phys orns and rings every time I fought a Sin.And you bet your sweet bippy that every sin, ever would be asking for a reversion to this.Edit: It should be stated that I'm a Veno in full dragon HA for those that don't know.Ever seen a Sin try to take out a full Str veno relying only on the damage from Condensed Thorn? Elemental pills don't work because they can be purged. And I purge through Tidal fairly reliably.
