Since intro gives a lot of damage on their "defense",I use energy regen. On all of my chacters in the team 😂 Meta build? What is that? No to meta. I choose the "freedom" (I build them however I want).
danjin is better in term of havoc damage buffer especially if you have S6 danjin with more atk 20% to all team if you trigger her forte, but the concretro regen for trigger her outro is quite slow than sanhua, so if you want more havoc dmg go for danjin, if you want quick rotation go for sanhua, sanhua outro buff basic atk 38% which is good for rover havoc while in dark surge state (forte trigger), sanhua S6 have total buff atk 20% too, and sanhua is by far the fastest 4* concretro regen if you play her correctly
@Ceizars you could have saied ihave the same echo set for both verina and bahizui but I just wanted to see if ican clear it whitout verina(your English isn't that bad though)
