My only suggestion of cheap blade and soul gold here is a training ground/area but more open and more dummies to practice on, since practicing 1 combo 3 times in a quest doesn't teach me the full effects of everything I have.
To get it out of the way - queues. At this point it's obvious prevention would've been better than reaction. I try to understand that servers cost money and server caps can only be raised so far ect. but there were a lot of ways to prevent this. My idea would be create more servers to take the immediate influx of users, then as it dies down if servers become dead merge them.
I only suggest this since I've played plenty of games that do this same concept, although I'm not sure how 'easy' it is for NCsoft to merge them. And for the 'overpopulated' servers you could stop new characters from being created, but instead of re-opening them so quickly wait for the other servers to equalize with them. To address the users all games have queues/lag/bugs when they start" is not an excuse, it's more proof that it should've been expected and handled better, if it happens every time, why did this game think it would be immune?
Kick feature: Currently the kick feature is a simple "Uninvite" that you just have to know is associated with removing a person from the guild. It's not intuitive at all.
Solution: Change text to "Remove from guild" "Guild Kick" or some other text that is more easily identifiable as a guild function.
Clan Sort: Level is repeated twice in this function. with one being a sort by the characters level, and the other by their rank in the clan.
Solution: Change the Level text to "Rank" or some other text.
Last Online: This is not a feature yet, but as leader of a clan this tool is indispensable. With Blade & Souls high item requirements for ranking up as well as Blade & Soul gold needed I cannot maintain an active clan without knowing if some members are inactive or not.
Solution:A tool that simply tells the last time they were online as seen in many other MMO's would be of great help.
Clan Advisor: Currently the "Officer" position is limited to one person. As I run my clan with multiple officers ( generally 3-4 so people don't have to be online ALL the time) this causes problems. I wish to provide the distinction that ranking up gives from recruit to veteran, however I'm unable to do that if I have to reserve the veteran rank for those I would normally put in the Officer/Advisor position.
Solution: Allow multiple people to be appointed to "Advisor."
Account Membership: I'm unsure on how this would work, but this could be a benefit for many clans, as many people like to have multiple characters, but are unable to be in their guild due to the space being pretty restricted in clans.
