I have up to 100mps download speeds and up to 20mps upload speeds and I am hardwired in with a static IP for my console. I have noticed that in any PVP or even PVE game I am always the fireteam leader by default. I am under the assumption that the Bungie servers ping the players and assign the fireteam leader to the strongest connection. Asside from Xbox server issues that happen occasionally I never have disconnection problems. I have noticed that players that I raid with or that I play IB with that are connected with Wi-Fi do have disconnection issues. When they get disconnected and then reconnect after some time, I ask them if their connection is wired or wireless, it usually ends up being wireless. Point being, before blaming Bungie servers which may be the case in some situations, check your connection, try a wired connection if you've been playing wireless. You may be surprised how much better your experience is. On a side note, in PVP my shotgun shots usually always connect and I attribute this to my wired connection. In that split second decision when it comes down to two shotguns, it'll be the hardwired connection that registers first giving them the kill.
