Also make sure soul swap is glyphed and occasionally soul swap you dot's onto another target (always just before it dies, but sometimes mid fight as well) so you get twice the ticks. You wont pull threat and if you do just soul shatter.
Oh and stick with INT Haste, whoever told you otherwise is wrong, period. Also, if you are in a group that is just destroying an instance, your damage isn't going to be good on trash and that is ok, your numbers will shine on bosses.
