I do not encourage people to be purposely lazy or trolling in game. I'm not either the last to ask myself questions about players level, sometimes. For a causual player like me, my level as just acceptable, bellow good, in other words, but not the worst either.
But I don't say anything in dungeon, in raid when I see some disaster or will not create topic in this forum about skill level of players. Why? I cannot encourage judgments or any kind of behavior that, in the opposite of a bad player, sounds like self-proclamed pgm.
I always think as a little too easy to say things as you do "I know I can be world first". Here comes the point, if you are not, be, don't find any excuse. Why Do I say that? Because there is no way for me you don't apply to yourself the rules you wish towards others. You want, do, you don't want, unfortunatly, following your rules, let the other be, without complaining. They don't have excuse, you don't have; they have, then you have too.
I'm well aware about the question of basics rotations. Maybe there are people who need IG how-too or who don't really understand their class. Do I have to condemn them? No. Sad, maybe, but no.
The basic difference is finally I do not create judgment to other if I cannot apply them to myself, otherwise, that would sound to me like hypocrisy.
The last point, since I saw self-proclamed pgm with savage stuff playing like **** in game, people trolling-pull and desipsing others, I just can't follow people who judge level of other. Self-proclamed good players are sometimes the worst because of their overconfidence and presomptuous state of mind. Not matter how good you can be, presomptuous people are to me like ****. Especially since I one day meet a real genius with true modesty. And many real genius are genuinly modest, there are that much easy they are unable to feel any competition with others.
Little edit : Rather than saying I don't judge, for a proper understanding, I should say I don't condemn and refuse to follow people who sentence. And rather saying they are like ****, they don't deserve we care. Please notice is not a sentence from me to you, there's just no way I follow you. Maybe it is my lack but I'm unable to admire anyone. There are too many things that fairly allow to relativize "awsomeness".
