Yeah man, I agree with you. I think that makes the spring version a lot more spontaneous than the winter version. Even if they didn't remove the whole fence - just a part of it - would allow for some degree of flexibility with MG bottlenecks and flanking around north etc.
As it stands now, though, I have on a few occasions flamed the fence during a blizzard, so nobody sees, then waltzed in behind MG's camping at the north VP. If it was a solid structure that needed heavy fire to get through then I'd be screaming for a change but as long as you can get through it yourself, its not the end of the world.
