It depends when you mean, when I joined PK CK with foudil it was impossible to win, once we actually blew up all quads and got him dead and reset but then they brought in 200 mobs and killed us all with pitbulls.
The top of landgrab, and probably the most visited one, I Think was when Kim visited the landgrab (and also kept people from spawning vehicles in the zone). There must have been 50+ people at fort at that time, not only the two sides but also a Group of spectators who just enjoyed the show. Getting rid of vehicles at claim rod, and putting turret at fort entrance was good things, I Think. Also, even for defenders, someone "friendly" bringing in tons of mobs to "clear the claim" was annoying, after all those mobs remained...
