I was actually thinking of Unerring Vision of Lei-Shen's potential outside of CDs, ofcourse this is assuming its uptime is really high (something crazy like 90% if not 100% given its duration). We'll see an increase in the number of lava surge procs, clear casting uptime will be even more which will translate in more (dare I say it) sustained DPS over the course of a fight, and in some cases those big Fulmination and Elemental Blast crits will be sweet not to mention a tiny bit of dps increase from Fire ele / Searing. That being said those 8k+ int procs look juicy though I want them
P.S: Btw Ryuke the 4pc bonus is not affected by Echo procs only overloads, think a blue mentioned this a few weeks back when they were getting questions about what does the 4pc proc from, and the Lava bursts cast during ascendence do count to lowering the CD when you first pop it.
