Let's say you are level 50 and have one of two choices:

1. JTM 2/3 and CB 3/5

or

2. JTM 1/3 and CB 4/5

Between these two options which will yield better DPS.

Option 1 would lead to a -3% DPS decrease in CB, and a +6% chance of JTM proccing.

Option 2 would lead to a +3% DPS increase in CB, and a -6% chance of JTM proccing.

My gut tells me that JTM is pretty worthless and I'd be better off with a +3% increase to CB damage.

However I was wondering if someone could make a valid argument against this.
