when i played u could stack a potion up to 64x which is ridiculous but still 16x or 8x a potion would be nice instead of only 1 nonstack, just my opinion
Yeah, /sp was a bit ridiculous because it led to pvp taking ages as people could carry way to many potions and just spam right click, making a lot of fights a lot easier and dragging them out. /sp was removed and has been for a few resets to make pvp fairer and also not make every fight last a really long time.
