I am perfectly aware that matt is hated. But that doesnt mean ALL slap players should be.
I completely, and I mean COMPLETELY agree with you here.
There are good people that play with SLAP. Take
Littledrew for example, nicest guy out there.
However: Aside from the ever-failing all-hated Matt, go have a look at
Incoming Impact, Resuming windows, necromonger and Grimlock, to say THE LEAST.
These players will NEVER admit a fair defeat. They will never admit that they may be wrong. They will lie night and day in hope that some delusional fool will believe them. Most of them, given the chance, will play unfair and NOT BY THE RULES. And it's only logical that most of those who have (more or less) a flawed character will be drawn to people like themselves. Hence, those much like Matt tend to play in SLAP.
This is what is wrong with SLAP. Most of your players are not bad players, but BAD PERSONS. No hard feelings, I mean no disrespect in this post. And even though this may sound extremely hilarious, there's an unwritten karma rule that BAD PEOPLE LOSE. Hence, your constant failures.
Change your people's behaviour and the rest of changes will come by themselves.
Good luck.
Oh. And as for Calum - he's one of the good guys. He'd feel ashamed to tell you face to face what's wrong with you and why he doesn't like you. That's why he isn't drawn to play with SLAP. Because he's made of something different from you. Something better. No hard feelings.
