Players need reasons to join the battlestation besides just ‘pvp’. Else you get a very small group of people actually using the battlestation. You need a way to make players experience pvp so they can start liking it. So I kinda like the idea of xp/item rewards to make pvm’ers get experience and try it out.
When Funcom/ark made “Rubi-ka Rumble” happen (3v3 pvp tournament). They had a small arena with 2 buffing rooms that open after a set time and the 2 teams fight. That would be perfect for 4-10 people or so. So it would be last team standing.
So you can sign up. The system forms 2 teams of 2-5 people. Would be best to spread professions and balance skill level of players. This skill level could be a score you get from the battlestation, you should also be able to lose points! A fun extra could be a leaderboard with these scores, more epeen!
Make this happen and I would be addicted for another 20 years
