shpook...your example is unbalanced
10+320=330
150+250=400
..
my point was more that if you have weapon a and b
a is 100-400 (250 avg)
b is 200-300 (250 avg)
if you continuously used one then the other you would notice the one with the higher minimum tends to lock ( make enemy go through recovery animation) more often..any decent char/build will have alot more than enough to make someone enter the recovery animation but the best have a minimum that could put them in a lock..
i reccomend having over 800 minimum at any given point with a melee character (especially one handers)

hope this helps =-)
