Blizz/orb is the best pvm cold sorc build, but only once you have all the required high end gear.
You need a lot of -res on gear, which allows you to max both blizz and orb and all their synergies.
Only 1 pt in CM (up to 4-6 at lvl 99)
1) now that they don’t share the same delay, you can cast both in alternance.
2) CM and infinity work only at 1/5 effectiveness against sundered enemies. -res from gear works at 100%. This build maximize -res on gear so you still bring all non-immunes to the capped -100res, while having better cold penetration against immunes than the standard builds.
Here’s the full build :

This is purely a pvm build.
Orb sucks at pvp and CM works at 100% in pvp so a pure blizz build is obviously much better if pvp is the goal
Most people will cold stack enough to make CM irrelevant so I think some people use both. In pub duels most people aren’t going to bother stacking so u might as well go for cheesy 1 shots I guess. I think most people at least go 1 point into orb for chip dmg/clear summons on blizz sorcs now though. Again just not sure how they prioritize orb vs mastery. Probably more mastery for pubs and certain rulesets and orb for tourneys
