I did multiple uber runs to test out the new frenzy dual wield act 5 mercenary coming in Patch 2.4. Here is the deep dive video! Let me know if you have any questions. Enjoy!
Interesting footage
Soooo would you say that A5 merc kills regular Diablo or other regular bosses faster than A2 merc at higher player counts? (Crushing blow gets less efficient at higher p-count)
The Act 5 Merc opens a lot of possibilities simply due to dual wielding 1h swords. You can go 2x Last Wish which actually stacks up to level 34 Might Aura. You can go Kingslayer+Last Wish which can clear ubers as shown in the vid. You can alternatively go Grief + Last Wish for speedfarming. There are of course more possibilities. Act 5 Merc is generally better than Act 2 merc for Speedfarming but it’s pretty close. For boss kills specifically, I would still prefer the Act 2 Merc because he has longer range attack + Jab.
