I agree with Ulic/Nihl here. Revan isn't exactly a counter to JWM. It's definitely not like Han Rogue and Thrawn. However, he provides a balance to them. Revan will not win against an equal number of JWMs 100% of the time, but he will win often enough that it will cause people to start questioning whether they should run something else.
The cool thing is, I think this actually helps NR become more playable as well. Since they have access to Han Rogue and Recon, and have a 120 dmg Cunning Attacker, Revan will struggle against them. All it takes is to lose that crucial init when Mara has closed in. NR wins init, Han takes a Cunning Attack at Revan (probably with some CF, lol) and then Mara cleans up to finish him off. If Han hits, and Mara makes all 4 of her attacks, that's 140 dmg even. It's actually kind of cool how a piece for the Sith actually boosts the NR a little too.
Oh, and emr, I think it's hilarious what side of the discussion you are on here. So far with everything else in this set you've been very vocal about apparent power creep. Now, the first time that many of the rest of us are really excited about a new piece that can shift the current meta, you're basically telling all of us that he sucks, lol. Just a funny observation. Almost seems like you just want to be on the opposite side of the discussion from the majority, no matter what side that is. I'm not saying that's a bad thing though, and definitely not trying to start anything. Just thought it was kind of funny.
