I don't agree with the "it's only a few cents" either. I try to treat all tournaments the same regardless of the buy in.
tbh the crap shooters don't bother me too much, I play tight anyway, but it can be frustrating when QQ+ gets called by some gross rags and they hit 2 pair, but the majority of the time you should come out ahead.
I also don't think that any freerolls exist that don't have some players with that mentality.
