Unpopular opinion: If someone has a K/D ratio of 6, 10, or higher and their game is **bleep**, it's clear they're playing with bots. I don't think it's that critical if players play with bots in Portal. The K/D ratio is only useful for discussions in bars or with friends, but if you get 3 kills and 30 deaths in the game, SHAME! I think it's fine if someone wants to play with bots, if players have fun with this mod, it's fine and they should play freely, because the ratio is just a number and if people are happy to see big numbers, that's fine. The most important thing is the battlefield. In conclusion, you can write that you can fly by flapping your hands, but if you don't prove it, you're a loser.
