Even back on h2 you didn't use a firewall to "knock out" connections if you had connection host you just blocked their ip from connecting to you so with it all being dedicated servers now you would just list which IP's you are able to connect to
Destiny is a sad excuse for an MMO.. There's no economy the grinding is terrible where as I have 20 hours on the game and am a level 26.5 my friend has well over 50 and just hit a 28 sorry but 25+ hrs to only be 1.5lvls higher just isn't worth it..The only console MMO that I would even consider...
Dedicated server or not when circle boosting your not worrying about host ,it would most likely be the same ol **** add
Xbox ip
H2 servers ip
7 ip's from participants fire wall on high
and one person from opposite team would do the same
Higher risk of ban/reset absolutely
