Well I know, not all of you reached high-level and this thread might be completly unappealing for you right now; BUT...
Let me tell you this: At the moment you need 15 keys to enter the dragon room. There is only 1 Zin General on each channel, who
dropps 1 of those keys, on condition you have the gear to kill them. So, u'll get 4 keys each spawn, makes 12 keys /hour overall.
So after 1 hour you still can't enter the dragon room. Now imagine, there are more players, than just one, who wants to enter the dragon.
Like 3-4 guilds with 5 players each.
Lets say each guild will get 1 Channel, so its 5h for just ONE player of each guild to enter the room.
But guys, that's not all... after u killed the dragon, which is right now by far the strongest boss u'll get just one of two Uppitems for 100%
And u just need 3-4 Scales/Claws each to upgrade your Stuff.
My suggestion is: Spawn 4 Generals on each channel and let the dragon dropp at least both of the uppitems 100%.
Ah I almost forgot it - there is only 1 Party, who can enter the dragon room at the same time, that should be changed as well, if the team is trying to consider my suggestion.
