well, before talk about, let me tell you that any strategy here can be good, if that is what u lilke
about OH stats sum... there aren't any numbers correct or not for a level... only can do this: the most, the better... for a reference, there are players who sum more than 1 million points... but the most people have them below 10k, at least at medium and low levels
Shame, from CF, cant be avoided, else that 4h protection u get after lose a CF
About raids, yes, in high levels is very frequent to be assaulted, what to do? obvious: fight skill, weapon, guards, all the better... but wallet players have the key, to buy the protection packs (guards who autoheal) and/or buy CC protection against raids for their parlours.
