In terms of 'choices' you need to look at theother stats. Haste is really the key because it contains break points for extra HoT ticks. If you are working towards a Haste break point, then you can drop spirit and even Int (in reasonable amounts). Theres plenty of threads with info on this.
IMO Mastery and Crit are fairly equal in effectivness. Probably based on pure numbers, Mastery is going to give you more - especially in 10 mans.
