I've killed my friends and party members plenty of times, though I will confess its usually because I'm more focused on a chat then actually healing the party. But those that know me know that, regardless of letting them die a lot, lol, I am a good healer. I outright tell friends yeah I was in chat sorry, lol. But if it's a random party I usually make something up like sorry button got stuck, lag spike, or I do actually say chat distracted me for a sec.

One of the worst things I hate is seeing a healer, especially a Scholar, be just plain bad. And not the normal, you can tell they are having a bad run, but the, this is how they play, how did they make it this far, run. A bad run usually has a lot of death, lol, but with a bad healer, you may not die, but the play style seems off. When I "fail" I will acknowledge it and say something to notify the party, or if I have a derp moment. But I will admit hating when the entire run is smooth and a have a derp moment, for whatever reason, and everyone bitches; like seriously!
