Here's a more detailed version of the battle that went horribly wrong last session, if you're interested;
Our horses were stolen during the night by agents of the big bad guy. So, we manage to track them to the beach and there along the waters edge to a small cove. The nights dark and foggy, so we can't see very far ahead of us. We send the halfling rogue up ahead to scout out a light source in the distance, which turns out to be a lamp. So, the halfing decides not to come back and let us know what's going on, but to continue forward, wandering into the fog. Our DM runs a very "act what your character knows, not meta-knowledge" game, so we're not sure if it's from magic or whatnot. So, to keep from losing him in the fog, half of us decide to follow. The lamp turned out to be a targeting device. A huge ambush group was hiding in the fog, and a druid aimed an entangle spell at us when we moved through the light. Half our party gets stuck in the seaweed that grabs us, most of the rest are trying to pry them out. I follow after the halfing to get him out of there, and run across about 5 combatants, backed by 3 or so archers, the druid and a really tough mage. Why do I say really tough? Well let's just say our party of 8 level 4 characters then got hit with a delayed blast fireball. I get beat down after a few rounds, and only after using a magic item I nabbed off an assassin (sort of a blink spell stored in a breakable glass sphere) did I get away with my life, and managed to drag the rest out of there. We would have been pursued, but our Mage had a delayed blast fireball scroll of his own that he unleasshed and managed to drop nearly half of the opposing party. We called the watch in the morning and they went in to check the place out, it was abandoned and our horses were still inside.
But I'm tired of there not being any cohesion, no one that can decide what happens. Our DM may often run things as a "I'm telling a story" sort of railroading a bit, so some players figure no matter what they do, the DM will make sure they have fun; but I WANT to be challanged, I want there to be a chance that we don't suceed. And is it wrong that I want someone in the party to make sure we're not making stupid decisions?
