It is a win and a fail at the same time , in my opinion.
Why a win?
Because those people that CB alot now can also make some gil , also if it is not big a income and you need the luck to win the lot on an item , yeah that's still a slight gils income.
You can find dynamis coins various Goldsmithng Smithing and others synths mats ( I have seen a dragon meat there 50k maybe? ).
Why a Fail?
Now is almost impossible find a mob to earn exp and Allied Notes , everyone go get them and keep them far from the fortification , a wave of mob is what 8-12 enemies? Vs 80-120 people in a zone , few lucky claim those enemies and kill them asap. Can be really frustating make some good exp out CB right now , but hmmm who know maybe it'll be back as it was before
