Valid strategies that sounds toxic as hell
List some things that will sound incredibly toxic normally when typed, or said. But is actually meant as a valid strategy.
KYS/KMS: Kill yourself. Sounds toxic as crap because it is often screamed out in a fit of toxic rage. But this is actually a VALID strategy in many games including league of legends. If it looks like you can not run away. It is probably better to survive without taking damage for 13 seconds and run into a tower or a wave of minions to deny the enemy xp and gold.
Run it down Mid: The most common meaning of this is simply to intentionally feed. But it actually originated as meaning "Push the wave down mid". Because you know... mid is the shortest route to the end game objective.
Feeding: Normally feeding is bad. And dying is the worst thing you can possibly do. A number of players get upset about kill stealing for the wrong reasons though. Instead of the penta or glory... the biggest concern is the gold bonus you get for last hitting. In DOTA 1, where the term originated, people were upset about kill stealing because there were a number of defenders who just don't benefit from the gold or excess experience. It's the same with league when anyone else but your carries get fed. The champion is still getting stronger.... but I'd rather a thresh kill me than a freaking Jinx.
Trolling/Camping: Obviously one of the worst things a player can ever do... to their team. Trolling is often one hell of a strategy to just force someone on the opposite team to tilt hard. I've personally ganked and camped a top laner for four kills. First was the gank. Second was when he TPed back. Third between the towers. Fourth in his base before any towers were actually destroyed. Last was when I spotted him trying to rotate. And yeaah... I kinda waited for him.
Troll Pick: In a game with over 100 champions, picking an off meta champion isn't necessairly bad. Chances are a number of players will only know at most thirty of them in and out. It'd be incredibly unlikely to find someone who knows the game so well that they can identify all of the abilities, weaknesses, strengths, counters, etc of any champion unless they were popular enough to be selected.
