Am I coiling it wrong? (a WHM OOM question)

[Hysterior]

this way I can target the boss and see him casting the big moves so I can Q up a cure II

I personally prefer always having my tank as primary target
For the mob attack I changed the chat settings and display only 2 things: party chat and attack the monster is making
So that I can see what he is doing while still having my tank as focus
I am not trusting that /mo healing
