A good rule of thumb, aside from 27-30/65/60 for Shadow tank stats
Not to really detract from the conversation, but I keep seeing this 65% Shield Chance (w/ KW) as optimal and It kinda has me trying to figure out whether or not if I'm hurting myself sitting at 29.12%/ 70.34%/ 59.78%. I'm using two BM PvP relics (on Shield, the other Defense) because I'm presently leaning towards more passive mitigation as kind of a cookie-cutter for all content.
I can probably switch out a few of my Shield Augments for some Defense ones to get that to 30%, but sitting at 70% shield chance is just so damn pretty. I do have the Rakata On-use Shield relic and the Campaign Absorb Proc Relic, so switching my relics isn't exactly pulling teeth, just looking for a second opinion.
