Dont worry, im much the same with around 200 games played, highest is 1647.

All i can suggest it just keep playing games, you will win some and lose some. When you've had enough for the night stop, pick it up the next day and carry on. Taking breaks doesnt hurt.

If you are using focus for your assist macros, why not setup your main char to set the focus on himself too. With my 4 shaman all my macros are identical on all 4 shaman. Works for me. Although i'll look into this again if i ever get past 1650, as most teams past this mark use tot healing a lot xD

Its ok to be German, the war is long since over, dont worry about it, all is forgiven.
