I love that the entire argument boils down to "We shouldn't have parsers, because it makes people feel bad to be told they suck!" Never mind that it could only be beneficial to a group as a whole to figure out what's lacking, and improve accordingly. The players that suck would be booted out anyway, regardless of parse. Because they do suck. And even without the actual numbers, we can tell how much they suck, just by keeping any eye on them. You can tell at a glance, watching the DoTs on the boss, and the buffs they get, who sucks at their class. All a parse would do is make it so those of us who want to improve can have a tool to help that.
