Im hittin 360 - 390 depending on how much I have to move in turn 8 (like gettin these super far away mines on the right side of the avatar automatically give a -10 dps straight) @ilvl95, honestly with ilvl110 weapon + half gear ilvl110 / crafted ilvl90 pentamelded you should be close to 380 - 410.
if you gotta catch the mines on right or left, the key is to get there after your gcd + auto attack are done, wait a bit on the mine spot while havin your back turned to the avatar so you re pushed back perfectly to continue dps. That and DFD should be up for 3 Dreads also
Otherwise. Wth is no briar tact in t6.
