A plea: If you weren't going to go in earlier, don't go in now.
Obviously there are times when this statement is wrong, but for the love of god if I assist ping because I am getting ganked and dove on 1v3 at bot turret and you just keep taking blue in the east jungle with my support (why is my support even over there. anyway) and then both of you decide not come over because I'm already doomed, don't bother to come in 12 seconds later when you both realize I got 2 of them low. Yeah, I realize I was being dumb and got caught out, but please! It's now a 2v3 at the bot lane. If you weren't going to fight in a 3v3 why would you fight in a 2v3. They didn't even use any important cooldowns aaaaaand enemy triple kill.
Just because I made a bad mistake doesn't mean I'm retarded and you should ignore my v-ping.
