Damian has 3/4 Borg set and I have a setting that is 75 shields 75 engines for that time when I'm getting a little focus fire but I'm waiting on my evasive or deuterium cooldown.
Sometmes he's like frankendefiant for a minute or 2. And I will look some more tonight to see if I can count off the Borg procs. But it does make sense to get proc'd more by cannons, as I believe that mechanic would work both ways. Offensive for cits, and more "crits" on the recieving end of your Borg set
At normal shield settings like 69/40 FaW makes it proc like crazy. But if I am focused fire and go into defensive mode max in shields and 75/50 in engines my 4/4 borg set usually brings me back from the brink or holds me over until me HE or team mates get to me.
It can proc once every 45 seconds, but think about it..
If it have a 1% chance of proccing, you would be almost certain it would proc when under focusfire from ships using CRF and turrets (Escorts) - I wont even try to guess how many bolts 3x3 turrets on 3 escorts shoot out when using CRF3
That is the problem my borg set procs more from FaW per shot than CRF. And every time I reach 100+ shields it almost procs continually for like 10 seconds. Last night I was going against some Penging Cruiser from CF and he got me down to 7% with a peng crit I went into shield mode and tanked him and and a nebula for about 2 minutes until a friendly came and casted a HE on me and then I was still proccing all the way back to 100% which allowed me to go offensive and kill the cruiser and nebula.
