24/15 will be a blast. First real sword is the Bastard Sword, but a strong, balanced starter is the shortened military scythe. Its gonna be slow, but after swinging it around, the sword will feel like lightning.
Might try putting the 2 points into shield instead of WM. WM gets better as you put more points into it, so 2 WM will make the difference between about 113 wpf, and 125 wpf. I forget the formula, but its very insignificant. If you do 2 Shield points, you can carry a shield that will stand up to arrows, giving you a tactical edge against ranged. You won't be able to charge them in an open field, but having the option to use it to gain ground and move to cover is nice. With a bastard / longsword, you can swing it in 1h mode as well so you dont need to redraw your weapon when you catch an archer.
Try a Skip the Fun character. You can spec him to 24/15, and respec them all the time now. Try out 27/12, 21/18, and 18/21. From there, even try 18/18 and 21/15 with full Weaponmaster. You really won't ruin your build unless you put points into power draw and horse archery. A lot of people play with little or no Ironflesh, but it really helps a lot.
