Mate, let me tell you the reality of the HoN community. Almost no matter what bracket you reach, nobody is going to be wanting to teach you how to play. If you do something wrong, everybody will flame you.
It's up to YOU, to get better. I've started in the 1500s same as you, moved up to 1800s and eventually 1900s and the higher I got, the flaming actually got worse. The HoN community is one of the worst communities ever, if you do something wrong, everybody will rage at you instead of trying to tell you what you did wrong (unless you're playing with friends). I still remember in the 1817+ matches when a 2000 psr kid who think's he is the best player ever flames the cr*p out of some poor kid who misses a stun or something.
