I try to stay out of casual vs hardcore discussion, but seriously just get the clears. Its not that hard. The final battle should be restricted to those who climbed. For another example beyond those given, dynamis xarc required all city clears and glacier clears. Please make people get some basic accomplishments. If you want easy mode go solo dyna on your bst or do Abyssea. Nothing wrong with a couple large alliance events that require clearing content before you get to the final battle.
