I don't disagree that more people would play BDO if the enchanting system wasn't pure aids, but that doesn't mean PA would make more money. 10k non paying customers still results in a yearly revenue of zero. TBH as sad as it is to admit I don't think BDO can stay financially a float without it current echancment system and other similar systems (like horse training), not because these are good rewarding systems, but because it brings in so much money from gambling addicts who are willing to spend thousands to feed their addiction. Us non gambling addicts aren't PA CEO's target audience sadly thus our opinion to PA CEO's in the end of the day doesn't really matter.
P2W games like bdo have low spender-nonspender ratio, as those games mainly financed by a few very big spender.
You can read about how this kind of games works, as there is a lot of study on the net covering it.
