A lot of people are complaining about the changes to carnage, mainly about the gore nerf and the removal of the root. Those might be problems but I actually think it will have higher sustained then it did previously due to the addition of the passive 20% armor debuff. Also I think it will be easier to get a full ravage off now because of the changes to force choke. Being able to force choke then gore/ravage and force scream(I can't remember the new skills name) with out being able to be stunned or knocked back by the person your trying to do it to will be amazing. Some utilities the jugg is getting are pretty op while the mara doesn't really get any thing new. Mainly the one that makes the jugg slow buff the movement speed of every one around them, I can imagine that being very annoying for all melee but more so for maras because they can only really remove the slow once with force camo i(f they spec for it). I've played my mara since launch I'm going to be leveling it to 60 first over my jugg. I feel if your a decent player you'll be fine on a mara but it might be more annoying then it used to be with the addition of more utility for most other classes.
