You can use Arcanist with Ascendant for more bleed dmg with shock. Also since weaken is buff to 90% crystal affix and cap is 200%, you can use crystal weaken. Goes great with effective . Effective work with ignore resist which can be used in the build too.
You could also use Barbarian %, Push the limit% , Glasscannon% , pathfinder set, Defiant, only need 2 epic toss affix as that buffed to 10 instead of 5 , 10+ talent like lacerate or use 5+ all talents , zealous, more block and dodge , some other survival affix, etc. So much to change it from what it used to be although it would change too much. This build is a testament of how far DQ has progressed. Suffering talent is fine too. Also you can have axe with 100% WD or ED. Definitely you can add more ED% too for improvement. I can see this build possibly shine again lol. Maybe keeping ruptured or using exposed mythic. Either is fine. More MS too if possible.
So much potential to upgrade.
