At first, thanks for all the great answers, opinions and views!!
If this is the case, then why bother asking whether or not weapon master is useful? It seems like you made your decision before the discussion even began, Lysander.
I'm atm lvl 31, and will be soon at 32, with agi build and high wm. But I'm thinking of retire (or maybe respec), cause I'm not sure if high wm was a good decission. So maybe convert 6 of my wm points to strenght, and give 1 wm point to PS. Or dont change the strenght, and put 5 wm points into IF. Or convert 6 wm points to agi and take 1 point more ath...
But I dont see sense in more str, since I kill most of others with 2 hits. IF would be an option, or more ath.
But I'm not sure what to do, so I thought, I will ask this lovely comunity. And now I'm totaly uncertain again...
