I'm a bit sick of people wanting to argue with me... can people please tell Anglarana (who wants to argue with me via private messages) that priest dots are not critting in WotLK.
He/she is mistaking the talk sorounding dot scaling with what is actually happening. One of the fixes that was discussed was allowing dots to crit but blizzard like the fact that not all spells work the same. Instead they allowed MF to crit and added the new SF ability that increases Dot damage equal to your crit percentage.
There is talk in allowing lock dots to crit and while i'm not up on the latest for locks I believe a talent was added (or will be added) that will have lock dots have a chance to deal double damage. While this looks like a crit it's technically an additional damage mechanic much like timbal's focusing crystal and crit driven events won't work on the double damage tick chance.
In any case, Anglarana... stop sending me private messages.
