I just noticed this for the first time today. I usually go into my fight list and attack random people to get my gamer points for the day. today I was losing lots of fights more than usual and I noticed that people over 300 and 700 levels above me are now appearing on my fight list! was this some new change in an update or is it like the "shark tank" in mafia wars now that I'm over 460 I'm vulnerable to attack from anyone regardless of their level?
The higher levels are on your fight list for you to attack if you want to. You don't show up on there fight list because your to low. So pretty much, you stay away from them, they can't attack you. But you can be hitlisted by anyone in the game now, regardless of if you have attacked them or not.
Just ignore those crazy level slayers (unless you can either beat them or you have a death wish) since as Lana said, you won't appear on their fightlist even if they appear on yours, so, just as before, unless you attack them, they won't be able to harm you. That happens since there aren't too many slayers on those levels. I remember high-level slayers started popping up around your level (450 or something like that)
fight list change? I'm level 463 now and the highest I've seen is level 473. I'm getting impatient! I guess I bulked up my attack for nothing.
