For me the hard boss on Stone Vigil Hard would be the 2nd boss where you have to use the cannons. After a point you'd get soo many adds come rushing you I'm not sure you could get past that unless you were on a healer. I don't mind them standing in bad stuff that gets placed on the ground or if the ground turns into a bad. I want more places to take them out in, but Im not sure how that happens unless we get this version is for squad only. Or they get tweaks to their AI or we get a true fall back to me command. Because they shouldn't be trying to hit bosses that go into a no damage taken phase or are like Siren where they become untargetable. They wont break off from those unless you hit disengage. Or you make them go after the adds.
