You have a lot of reaction proc and status proc twitch issues in that setup (health is low on mob, combo points, hot streak procs, eclipse procs, opponent dodges, slam proc is up, etc). Deciding to forgo even reacting to eclipse procs, spec out of hot streak or what is going to hurt.

Some of the mob turnover, from one target to another, is tough with a mixed group it seems. Where with other groups if the mob is left at 2% aoe damage will get in soon enough and you just move on.

Also with melee sequence casting hit capping is likely very important, if you expect you rogue to be gaining combos and landing finishing moves always you need to do so, otherwise things get gimped.

A mixed physical / magic group is going to be a bit low in damage overall I would assume, especially in fights where our dealing with cleansing spam for example.
