currently in pvp i’ve been running a 20/20/30/0/0 hammer build and it works pretty well. i spent a good portion of yesterday on skill calculators, comparing the numbers between the standard 30/30/10/0/0 and something like a 10/0/30/30/0 or a 0/10/30/30/0.
what i found was that with those defensive builds, you gain a TON of armor and vitality and only lose a little bit of power. But you also lose a very large amount of crit%. So needless to say, the standard GS build had a really high crit chance, but only slightly more attack than the defensive build, and was severely lacking in HP and armor.
Of course this is all before factoring in the bonuses you get from choosing various traits, which mostly depend on your playstyle.
TL;DR, i found my 20/20/30/0/0 hammer build to be a really fun and viable middle ground between the two.
