Kind of late in c-rpg tweaking to do anything about it, but agility is weaker than strength. They should have removed the free WPF gain, or scaled Weapon master differently than they currently do, but it's far too late to start tweaking stuff like that (unless they want to give out free respecs, which they don't).
Tydeus and some other players had come up with solutions a long time ago to make agility give more passive bonuses (like strength does), and to even the builds out a little bit. There were these same discussions a year or a year and a half ago, but I'm far too lazy to search the forums (but you are free to go ahead and do so and bump them, because there were a lot of good suggestions).
You are better off (at least as infantry) stacking more strength than agility. I think the EU people tend to have more balanced or agility based builds, so that's why you see a lot of them disagreeing and complaining about 180 wpf 27 agility katana users and thinking "god I don't want them to swing or move any faster"
