Pessimism
There's a difference between pessimism, and realism, but most people don't really know this, and kinda just say someone who is realistic, is pessimistic. Example, someone who is pessimistic at the start of a match, would say something like, gg we lost they've got so and so on their team etc. etc. Someone who is realistic would say, this is pointless, we're down 22 kills, they've gotten dragon 4 times, and baron twice, we're not winning this. Like, I just really wanted to clarify this, because everyone thinks I'm pessimistic! D: I'm not trying to a negative nancy, but if we're losing really badly, I'm gonna straight up and say it, "Hey, we're losing. Badly might I add, we're not going to win this." Afterwards, I start a surrender vote. If we don't surrender, I'm okay with it, I'm not gonna intentionally feed, not gonna AFK, I'm gonna try to help our team win. After a certain point, it gets ridiculous, and I get annoyed. I think everyone is too optimistic in this game. It's nice to turn things around, but there's a point where people can't turn games around. Veigar with over 1000 AP and 32/5/15? No no, you're done, let's move on XD
