In my recent games I've come across several level 5 honor players, some of which were nice and definitely deserved it. However *most* of them were actually more toxic than other average players, even level 2 honor players. So does the honor system actually help promote people to being nicer and more sportsmanlike or is it just another way of keeping the players playing to get the highest honor level? Perhaps riot should not relate sportsmanlike conduct to honor levels anymore, as they clearly don't mean anything.
Even myself, I'll admit, I do flame sometimes when I lose my temper, and (very rarely) end up offending someone or such, yet I've never gotten any warnings or such, and I'm honor level 4.
