Stick around. It becomes pretty easy to tell a new/casual player from a bot.

Even a new guy panics when attacked at the ice. Bots rarely, if at all bother to react to being attacked. Casuals are inconsistent with coordinating attacks, and while veteran players can take you down in seconds, they can't do it with the sheer speed or typical zerg behavior bots do. I can also say I've seen bots completely ignore someone standing right next to me and attack me or others. To make sure of it (as seen here) I got their attention, then ran straight to the same player from before, and they didn't touch him.

As for explanation and leadership, normally I'd be sympathetic to the plight, but after writing two guides, making videos, giving field commands, and STILL seeing some of the same people make the same costly mistakes, I'm a bit hard pressed to remain so patient, especially when half of them don't even care so long as they get XP.
