Maybe so, but can anyone tell me why? or just that they're better thatn me which is the essence of this thread anyway?
They got that way by practicing & learning from their mistakes. You will get better, it just takes time & AH has a steep learning curve.
On the score/skill thing. Score represents how well you understand the game (i.e. gaming the game); for Pete's sake, I am ranked #10 in LW right now! Which only shows I understand a tad about how to "do well" in AH. Skill
may be inferred from score, look at a player's k/d ratio and hit % in FTR & ATK modes; k/d & hit% are not the be-all/end-all to measure skill of course, just a rough guide (IMHO).
Keep

& soon you can be a regular
