What just drives you nuts in LitRPG? For me, it's players who are just bad at their game. Not n00bs; we were all n00bs once. But characters who are allegedly skilled, who do stupid things like deplete their magic halfway through a fight, or deliberately pull more than they can handle, or who otherwise just make me shake my fist at them because whatever crisis they're in is self-inflicted. Poor gameplay should not be the driving force behind the plot unless you're deliberately writing an unskilled player, IMO. What are your pet peeves?
