It would increase the fun of pvp and mass pvp.
it would be like giving all the magic classes 45 extra magic since the strength could be restated into magic but a physical class could not do so due to the fact that magic is useless to them therefore not being able to restat the extra points achieved. Sorry its late and I'm not really watching my English. Hope you get the idea lol.
Obviously not , don't think it's even required an explanation to this
Physical class could use the extra dex.
