I got two. The first one works with bombs. The other one, I participated in it in person in late August 2009 : 40 players were guarding SAD, around the entrance grid (CA, Rocket Launcher, all that stuff). We were approximately the same number. As I remember, 15 entered the main entrance, and got shot. The rest spawned using a car, in SAD's parking. At the other map's edge. And we won. So there's always a way ;p
For the Base to Base thing :It's already possible without taking risks. My suggestion would add an optional feature that would put risk into that operation.
Do you really believe, that someone will be dumb enough to set caravans to trade? It makes no sense... why would you wait with your valuable stuff for tons of PKs?
RP? PvP? Oh wait, having many items is much better than having fun, I forgot.
surely it is good feature for PvP, as there will be more instances than just TC... but PvP and trading and RolePlaying are different things... I am a trader in-game, and I would love to be able to trade to players while traveling with caravans, but we both know it is just a dream, it is impossible because of PKs, suicide bombers, and so on... I love role-playing, but I dont like playing a dead corpse...
That happens if you go alone with your level 3 char. Take a few high level guards with you (a caran should have those) and defend your stuff.
