If you're only interested in PvP then pumping STR AGIL and CON is probably what you want to do. Switch STR for PER if you are counting on archery coming through in a later update
If you're interested in other aspects of the game then it's worth balancing, which means adding INT, CHA and whichever of STR and PER you don't actively need.
It's not that hard to balance and raise stats at the moment anyway, with the speed of hunger you can go through a chest of baked goods in less than 4 hours. A lot more if you want to grind it by wailing on a brick wall with a heap of tea around.
