That's true, but I think maybe they could get 1 or 2 attack strength OR speed
Max amount of overall stats is 5 for light poke. Either adding an extra stat would make it unbalanced, or exchanging some reach for strength would make the weapon have a weaker poost. That would make it be quickly disregarded and left as a mediocre weapon by many. The 5 reach stats are what make it so unique and good.
