even if your one of the best pikemen in eu id say go more str 21-18 like gurni
the reason is simple. every mofo is going to try to shoot or attack you first as your a piker and an "easy" target. that and when you get stunned from a block it usually results in a hit, but mostly i think 7ps is nice
thats just me last time i used a pike it was mw and i was 24-15. I didnt have many clan mates playing with me so most of the team used to abandon me when confronted by the byz blob so i need ps to try to hurt at least one
with your clan mates and team work 15 str might work but you are one of the best players im sure you can work it out
