Without mindbender, there's shadowfiend during lust or when you really need an instant cast, but it's not much for dps.
As for CoP dot weaving, it's not that complex. It's memorization, and it isn't that good for DPS outside of a few single target fights. The obvious way to play COP replaces mind flay with mind spike at the expense of never using dots. Dot weaving is a non-obvious way to play where you apply dots once you're at shadow orb cap, and then you can extend a plague/insanity/mind blast rotation for long enough for your dots to tick through without being removed by a mind spike. You just have to memorize the cast sequence required to accomplish that. Oh and for your memorization efforts, you're rewarded with poor single target DPS.
As for "procs," the only ones that matter are when playing AS and your shadow word pain crits. That generates a shadow orb, and the AS playstyle is all about generating as many orbs as possible and spending them on devouring plague without wasting any. AS is a fun play style, but it's not as complicated as snapshotting was either.
