Interesting build. I'll try 15/24 with a warhammer first and run around for a while with 4 shield and 5 WM.
Did the 15/24 with warhammer and although the speed was nice, I had the shittiest games ever. Maybe because I was tired or something, but I had a 0,5 kdr on average (which is quite bad). The worst part of the build wasn't so much melee, but getting hit by archers. 2 hits meant a death (1 hit from an arbalest).
Falka did spark my interest with his build, but I'm going to try the inverse: 24/18. At level 32, that will leave me with 8 PS and 6 athletics instead of the other way around. Also, 59 hp coupled with some loomed medium armour and gloves makes the build more durable.
The thing I'm going to test with an STF is the 5 WM. It will most likely take me half a year of playing to get to 33 from 32, so I'll have to deal with that for a while.
5 WM and 18 agility is about 145 wpf, add in armour weight and I'm left with 120 or so effective wpf. I'm curious to see how it works out.
