This stat does the exact same thing that mastery does except it works with every spell and it's instant instead of a super slow 6 sec HoT. Renew gets the most benefit off this stat because each tick can multistrike individually.
2) Haste (Provides the best synergy with the brand new Sanctuary chakra, allows faster uses of CoH because of faster renew casts and boosts substantially renew healing which is the primary filler you will use in raiding).
3) Crit/Versatility/Mastery (All these stats are roughly equal, most dungeon gear that has multistrike comes with either crit or versatility so pick whatever you can find, versatility is usually the better stat here because there is no rng component like there is with crit since it's a flat healing boost to all abilities.)
In general avoid mastery as much as possible because the direct heals you cast in raiding are almost non-existant outside CoH and sometimes PoH. For 5-mans mastery is mroe valuable since you cast a lot more of direct heals but for raiding it's pretty bad.
