I had to stop a little early to deal with a puppy so stopped at 1,500 casts with the LB parse and 600 Lava Bursts on the 2nd, uploading that as first progress. This is from the ptr I included a screen shot of the addon I am using. It tracks the blizzard UI and records the number of times the cast bar was generated using certain abilities. I also did not equip the VLPC so that count not skew the results. Thus the count of lightning bolts cast is accurate.

LB:
I casted 1,500, got 1652 recorded casts putting the proc at 162 which is 10.8% proc chance.

Lava Burst:
I casted 600, got 693 recorded casts putting the proc at 93 which is 13.4% proc chance. I unequipped 4 piece so all the Lava Burst were hard casted.

Chain Lightning (cleave total of 3 targets):
I casted 1720 which would have cleave hits at 5260 total, got 5893 casts putting the proc at 633 which is 10.7% proc chance.

Flame Shock:
I received 4622 dot ticks, got 765 Wrath of Tarecgosa which is a 16.5% proc chance.

This is all the testing I could muster tonight so will continue tomorrow to get a larger data pool however it appears the hard cast proc rate was lowered to 10-11% which the dot tick proc rate remains unchanged.
