Actually, historically, that's always been a pretty good argument to rework things in IC2. When things are underused, they get buffed, and when things are overused, they get nerfed.
I do admit, that has happened a couple of times, the only problem is, i don't really think these buffs are enough to make them usable, with the likes of buildcraft, mystcraft etc. I think they'd need a MAJOR rework to even be usable because, as i see them at the moment, i don't really see something they can do that something else can't. I know i shouldn't be saying "oh well this --------- mod fixes this" but, the way i see it, it is true.
