Dukoo, I think the difference here is that you are only rerolling low end stuff. If you could reroll and get a nuke like folks did before then I would understand. I assume that a sentry gun is less likely than just rerolling to a car or UAV. I really like Hardline...once I saw it, I stopped using Snatch & Grab...taking emp nades in place of the slower thaw time.
I will say it is awesome to throw an EMP nade on someone, then manually thaw them, and thaw them twice as fast.
I love the mod - although a some folks seem to lag pretty badly. I usually play with a ping of 50 and I've noticed the level of pings that "lag" around the screen have been reduced. For example, It used to only be Prinny-type pings around 300 that lagged around the screen but now folks around 200 are doing so. Not sure if that is the result of the mod or something on my end but it does make some maps tough.
