I am not sure that I understand what you mean Kish. Stacking wands with like charges would not reduce your number of wands at all. It already happens in the Bag of Holding. Where "like" charged items are stacked. This would simply be a convenience issue for the inventory screen. Also it would really help out before obtaining the BoH.
For example, the number of wands stacked could be displayed in the lower half and charges in the upper half. Ten fully charged wands of Lightning with 100 charges each would then not take up ten slots. Now they would take up only 1 slot with 100 showing in the upper half and 10 showing in the lower half, etc.
Ahhh...it just occured to me that you might have thought I meant a merging effect rather than a stacking one. No, I agree with you that would be quite detrimental
