I guess 5.7 is good, but i am using armor with knockback feature which made the whole thing better/worse depending on situation. For example i want to kill a big pack of monsters, but knockback pushes them away from a range. Good thing - doing Bremmtown upgrade - pushes mobs away from you. Also i used gorefest a bit - works good, covers the area with a rug that does damage. Can be crafted on gloves, body armor, ect. Also i dex crafted boots/gloves + shield (banshee proc which i never seen lol) and reached max block. Fire/cold is working for me, less moons used.
Edit: might actually try broadside assassin a bit seriously. Just curious of the potential compared to sorc.
Edit 2:
Current skill plan -
?v=xvc&class=7&lvl=120&bonus=1111111111111100000&skills=1_30_0_0_0_0_0_0_0_0_1_12_29_1_10_0_0_0_0_0_1_1_0_0_0_1_1_29_0_0_0_0_16_1_0_&mg=1101&sos=3&name=Reached max block and around 300k defense with ice minions around. I still miss a lot of sigs but i already puting points into vitality since block is maxed and AR is over 80k. 18k hp with moonstrike buff for 10s. Managed to do all upgrades and bremmtown ghost is a joke now. Dragon boss is a bit tricky since i had to sinchronize fullisade to be off cooldown when facing him. Took more than few tries

Still lack the after kill procs on this melee sorc. I have Sor from deadfall and nova bomb from amulet.
