If you want to exclusively backpedal with polearms, which is the EU metagame, go 18/21 and enjoy getting one shotted by any decent NA player. If you want a good build, do 24/15 with maxed iron flesh and power strike, and 0 weapon master. 5 athletics is more then enough to completely dominate people if you are remotely good at blocking, holding attacks, footwork, etc. You'll have nearly double the HP of the 18/21 builds that max weapon master and all of that dumb stuff. Maybe high agility is better for dueling (not really) but you are just so gimping your build if you dont max ironflesh and powerstrike and have as much of it as you can for battle and strat. An NA player that gets some of the highest kills in Strategus matches, Allers, literally has 3 agility. He rips these coordinated EU teams apart regardless.
