There is no dedicated server in PVP ( the hybrid server/ peer to peer parts is only for pve ) Being the host give you a peak advantage over other player If one player have poor connection in a lobby it makes every other player a bit laggier Being the host give you the possibility to double connect your shot on laggy player : ( two tapping hand cannon without a damage buff for exemple ) You can force host by artifficialy decreasing your ping by using device like a Gaming rooter / change your dns ports or using a vpn and changing your NAT type to NAT 2 to Connect only with player of your region. -> it’s not a lagswitch or a ddos attack so it should not be considered as a network manipulation but it should definatly enhance your gaming experience. Remember that destiny 2 was originilay planed for release on PS3/360 , back then all the fps games used this tech of peer to peer connection and its technicaly very difficult / likely impossible to change a feature like this in the core game post Launch / mid develepoment so do not expect dedicated servers in pvp to be a thing.
