Ow absolutely, I omitted it because the convoys are pretty much a given, I got 9 rations today, so worth it. But I don't have to participate in the rest of the fights for that. Obviously *someone* has to, otherwise there's no convoys, but beyond the first 3 convoys I just don't see the reward in continuing unless you happen to get in the top 5 or something. It feels like you break even except for having a chance at good loot with the convoys. (which is nice, admittedly), and a tiny tiny chance at the reward for killing one of the mobs inbetween
