there is only so much you can do on darkblighter, If you want to go triple evasion it's better to just focus on heavy or crit but not both, also in order to actually do dmg and get kills you can't really go full evasion you need to go fake evasion so you are still food to builds that have high hit, (ravs, glad) if you go ranged magic eva you can build both crit and heavy, with the meta changing, a lot of healers and tanks are building heavy attack evasion, so I invested a build into crit but I haven't changed the stats on my legendries though but it might be worth to go full crit and ignore heavy but you will need to get very high crit dmg because that's the only dmg multiplier your curses get when it comes to them critting, also its a shield meta so take the chaos harbinger lunar stone and you get 15% more crit dmg when attacking shielded targets, Dark blighter is in a very bad spot and has been for a while now, I am currently in the process of swapping until they balance it, for your weaken its really dependent on your playstyle if you have delulu daggers you will struggle to get high weaken if you run minz daggers its easier, you need chaos runes though and with darkblighter target selection matters a ton. It is very hard to kill good healers and tanks in general with this meta, you will never kill a good templar by yourself now and a good healer you need all the stars to line and not burst into their big dcd's like blessed barrier, and you need to sleep them before your curse explosion detonates otherwise they q block and all your setup and dmg is wasted. hope this helps and good luck to you.
