How ever hard it is for you to believe, you being stronger has higher odds of you winning, which doesn't guarantee that outcome.
Odds are a funny thing, as they only try to 'predict' the outcome with weights. The higher the odds, the higher the chance something happens.
Try flipping a coin, you have 50/50 on which side it lands. If you flip it 4 times in a row on the same side will you question reality itself, because something improbable has happened? Maybe the coin was made in such a way? Nonsense, but that is what you sound like in your posts.
Arena fights are just a probability calculation, you can't always win even if you are favored. You being stronger means you have higher odds of winning, it doesn't guarantee it. So when you loose, even a couple of times in a row it happens, nothing is "made that way" so that you loose 1 in 5 or what ever, that's just how odds and probability work. It's not always adherent and pattern-like, there is always deviation so sometimes it will happen more often, and sometimes you will win unfavored fights, it's just the way it is.
Do not resort to insulting other posters or constantly tagging teamlers with the same message when you have already made your point.
