I'm in the middle with this, because we can buy HD/Enriched Elu/Ori already, so if we're trying to avoid P2W, we're already not. There are so many ways ingame to earn a bsb, and I'm super happy for that, because these things were -rare- on another server, and many others, which made upgrading just torture.
I'm not sure if anyone is aware, but if you buy an Enriched box of10, you get free bsb within it. Technically, this already exists, just in small amounts and very indirect. I personally would like to keep it this way, and putting more things for muh coins, may cause people to just BUY their gear and afk and complain of boredom. I'm more concerned on the impact of activity, rather than P2W. There's a valuable resource out there, and the only way to get it, is to play the game. I think that's important.
As for the - nothing worth donating for - then you really haven't lived in luxury yet @_@
You can expand your inventory
You can add more storage (you WILL need it eventually, and you will love having it)
You can change into previous classes (which is savior because some 4th classes look dumb)
You can buy HD Ori/Elu to upgrade further beyond 10.
You can buy a kafra storage box so you can farm all day on a map without going back
You can buy a tool dealer box, so you can farm all day
You can buy a lot of useful starting gear that is super beneficial early game and necessary late game, like rideword hat, vamp teeth.
You can get a permanent halter lead
You can buy an infinite egg hatcher, concentration/Awakening/Berserk Potion
You can buy Guyak Pudding
All of this is BEFORE the costumes, which EVERYONE will look at and consider before starting.
