2h vs. 1h proc rate

[khofuswiftclaw]

I remember a while back reading someone explain the proc rate updates that happened in the last 3-4 years.

The gist of it was: Average of 2 procs/min with max dex in the primary, and 1/min in secondary. 2handers average 3 procs/min since they take up both slots.

Even though I am 99.999999999% sure I saw a GM describe it in this way, I'm unable to find it in the patch notes and having trouble searching the many many years of posts on this topic. Me and many other players have been taking this as gospel for several years now.

Anyone have any information/links on 2h proc rates and whether they proc at a rate of 3/min with max dex? I remember it being explained in the context of the new patch somewhere but it might have been on Discord.
