Did a very quick skim over your logs (as in around 1min), and I can see some fundamental rotational issues.
1) Cons uptime could be higher (this increases your active mit amount, and self healing amount) - Aim to keep it down and to be in it
2) Seraphim use very low - Looking at some fights, you go as low as 1 cast over the entire fight, at this point you shouldn't use that talent....
3) Final Stand - You appear to be using this for raiding? If you go with hand of the protector you may yield more survivability results as it reduces the CD on your self heal (which you should probably be using more)
