I think better train at rome till 120rb after this you can try sharks :P
but sharks hit more so water need always heal and water exp better at rome till he low lvl :)
Because I was training my alts on sharks team 100RB+(w/o pets) sharks hit hard so water was always heal and lvl up slow and at rome pango dont hit that hard :P
Anyways i prefer to train on places where i can wear my EQ ^_^
