well you can focus only on pve but they are activities that are somewhat nauseating ... when you say you want pve you want to furnish and furnish pve in bdo it is trade, forges, alchemy things like that. if you want to furnish and furnish you can run the risk of being attacked by someone.
I think bdo is one of the best mmorpg of the moment. top for graphics and activities to do but the community is really toxic and some things there is too much difference in price or monsters level and the risk of being attacked by someone is really boring.
