I also did some math yesterday and found that 30/0/0/10/30 is superior to 30/25/0/0/15 regardless of what weapon setup you pick. My numbers were a bit different but the trend was the same 30/0 gs+axemace is about 4% better dps personally
than 30/25, and when you factor in Empowered Allies buffing the whole team, the comparison isn't close at all.
Additionally, I did about 3 hours of playtesting in game DPS tests on my stream last night and within the 30/0/0/10/30 build each weapon option (either GS+axe or Axe+Axe) had approximately equal kill times on any boss that lasted more than 2 weapon swaps. For example a generic 3w/m/g team with all gs+axe mace warriors killed the evolved destroyer in 18 seconds from the first hit. 3x pure axe warriors did it in exactly 18 seconds too.
As far as why 30/25 sucks here goes...
1. You have 3% less chance to crit base than the build with 0 in Arms which is a lulz. It also has 15% less crit damage.
2. The 30/25 build maintains an average of 2 stacks of vuln 100% uptime on bosses. Forceful GS maintains on average 3 stacks of Might. I think a lot of people overestimate what these two traits do. the 2 vuln stacks are nice, I'll agree. However, the 30/0 build maintains 2 stacks of Might from versatile power so these roughly cancel out because I am also assuming in the Forceful calculation that all 3 hits of WW hit everytime, which we know is bs.
3. I only assumed 3 boons for Empowered, we all know in a real boss fight that is a conservative number. The more boons 30/0 has the further ahead it goes. the 30/25 build does have the 10% damage vs bleeding buff, but the difference in base damage modifiers is only 4%. Which is canceled out by 2 boons, and even without the two boons 30/0 is superior so adding them in is hilarious.
4. You have the ability with 30/0 to bring empowered allies which is basically adding 750 power to your team dps, which is a party-wide buff that 30/25 has nothing similar for unless they can bring 2 copies of banner of strength that stack.
So all in all, 30/0/0/10/30 is the superior trait spread for DPS regardless of which weapon set you use
. In practice pure axe and gs+axe (both using 30/0) have virtually identical kill times in any fight lasting longer than 2 weapon swaps. The gs pulls ahead in shorter fights, and fights where the boss is pushed against a wall.
