If u do not want to ghet bored i suggest u to go with gap 9 till lvl 40 , then u can ghet free powerlevel from ongs , huns , sungsungs , academy , then close gap till u are 60 and go dw tomb so u open gap again till u ghet rid of tomb , u will be full farmed as a legit cuz u will never see lvl 90 +
