Most use branto ribs (or whatever they are called) titanasoir parts and giga hearts as currency to get things from the admin because it makes the server run smoother and encourages them to kill them
ARK Island Serv has no dino limitation come join the server I'm not and admin but it's fairly boosted and I already have 7 Brontos raising more tonight after work getting ready for the admins raid base for good loot
Lets be honest they people that ban them from there servers shouldnt be running servers any ways it means there internet is shit no trouble from the server i play on and 4 brontos at a time harvesting only thank that lags at that time is the name of items that i gather
Dodecs,ankys,brontos,stegos, anything that harvest high amounts of resources with the boosted stats makes the ping spike I usually just disable the saddle engrams.
