Mirabis has said several times over that this CR is not yet optimized for PVP, so to the folks buying it and expecting it to be top notch in that regard have failed the basic function of research. He has also said that he is working hard to satisfy those PVP needs by working on collaboration with some top notch PVP CR writers despite having little to no interest in the PVP side of things himself. Have patience and let him do his work, help him by constructively pointing out the shortcomings, and back everything up with logs so he/we can make some real progress instead of a flaming contest.
Despite not being "optimal" for PVP I have a 2200 RBG rating and a 1850 2's rating(low mostly due to a lack of interest in boosting it higher, I use my Resto Drood to carry a lot of my alts to gear them pulling his rating down). Is it perfect? NO. Do I fight with it and get pissed at it? Yes. Is it the best thing available to us for PVP? Yes. For PVE? Yes by a mile.
As for Stars I have very very little exp with it, but my funny story is this: I joined a pug RBG group because I was bored the other day and a RL friend was in the group, after joining the comp became such that they asked me if I had a Boomy spec because one of the leads had a friend he wanted to come on his Resto Drood. I lol'd and said that I had recently picked up the spec but was very inexperienced with it, but they asked me to try anyway. So me in my full Prideful Resto gear, a spec I have maybe an hours worth of experience playing, and a CR I had yet to do any real tweaking on ventured into a PUG RBG. In fairness this group was really really bad despite a 1700 MMR and several 2k+ exp players. We got WSG and my poor Boomy proceeded to ROFL stomp every Mother Trucker in the BG. TOP damage, and Top kills by a lot, it was funny to watch that lazor chicken go to work.
There are many things to tweak, babysit, and generally just live with but it does work with a little patience.
As for the PVE side of things, there really is no argument I show up in mostly PVP (Prideful gear) to SOO Normal pugs (through OQue) and endure the instant "Um this healer is in Pee Vhee Pee gear..." barrage and after much debate assure them that I can hold my own... Then proceed to embarrass every healer in group nearly every time. I don't raid much, but when I do this thing stomps the Shit out of 75% of the healers I end up grouped with, and I am in gear that should not even be close to competing with them. If you cannot replicate OP stories like this in PVE then you have something not setup correctly and should provide logs and look for settings feedback, or you have an addon, plugin, botbase, or something else that is interfering.
Edit: The Boomy story is a lot funnier (in my opinion) if you imagine Samuel L. Jackson reciting it
