My enthusiasm was high enough(11). Also my OS was much better than his OD, instead his OS was equal to my OD. Giving the fact that I've chosen an outside tactic i was expecting to perform better.
This game should give better insights through ratings but they are confusing. I remember that I had this problem some time ago, I had better ratings but I was outscored like 4-1 in 100 shoot ratings and I was told that rating isn't everything but also the 100shoot ratings is important.
I'm not sure how the PP100 for his PG was so low or if that's accurate, how he destroyed you from beyond the arc as he did, but given that he looks to have been a deadly sniper both last season and this season and since your defenders against him were a pair of 9k guards, it's not too surprising he went off as he did. I have a feeling that your run and gun hurt somewhat too - I'd guess that a motion would have torn the 2-3 up while the R&G caused too many quick shots when a few more seconds would have found a higher quality outside shot. But even with all that I think you were unlucky to lose, but the effects of CT vs. TIE aren't really reflected in the ratings.
