Except BF4s servers and netcode were a colossal failure, and the game stayed in that down right offensive stat for well over a year. IT. DID. NOT. RUN. SMOOTH. Just go on YT and search Pwnstar, he was one of the biggest battlefield YTs and stopped playing the game because he couldn't support what the devs did. Also bf is effectively an entirely multiplayer game (how many people really care about the campaign) with a large amount of very serious players, so they needed dedicated servers way more than destiny does. While destiny is mainly a pve game which doesn't need dedicated servers as much because of that not to mention the relatively small portion of players who do play pvp aren't as serious or "hardcore". Lastly, if I recall correctly the fact that BF actually uses 64 player servers actually helps them when it comes to using dedicated servers because they don't need to buy as many, 1-64 player server or 5ish-12, 10ish-six. Obviously dedicated servers would be awesome and i wish we had them too. But it's just not a fair comparison to make between a pvp game with lots of hardcore players (where many people buy there own servers) to a mainly pve game with mostly casual pvpers which would need way more servers (5-10x more).

Then explain why Halo games all ran smoothly? They can just do what they did there.

Up to halo 5 all halo's have run on a peer 2 peer connection the same has Destiny. Their was issues with the connections as well. Standby and lag switching were a big thing as well back then. You can't really compare Halo to Destiny when it comes to that.

I didn't have issues with Halo. Halo 3 sometimes when there were lots of explosions, but for the most part these games ran smoothly. I haven't played a single match in Destiny Y2 that didn't have at least a little lag. I think it's because Halo used CBMM, not SBMM.

Just because you didn't have an issue doesn't mean there wasn't issues. Just like someone people don't have issues playing Destiny. And I believe SBMM wasn't there during year 1 of Destiny

What? I thought we were talking about bf4? Now you completely switch? Do you admit bf4 did not run well for ages after it's launch? And that it's not a fair comparison because both games are fundamentally and completely different. How about you explain why Halo games all ran so smoothly? And you master coder can explain how they can do the exact same thing to destiny, how they can just completely reprogram the game and rework everything, completely starting over. How is this the way you have a discussion with people, make factually incorrect statement about a game and compare it with a completely and fundamentally different game than when some points that out you completely switch and go "explain why this game worked so well, they can just do that because reasons".

BF4 servers weren't laggy. They ran smoothly for me every day. Halo and Destiny are made by Bungie and have quite a bit of similarities. You said BF4 had dedicated servers because the servers had 64 people. Well, Halo, just like Destiny, is not anywhere near that. It's also older, so the technology wasn't as advanced. I see no excuse for all this lag.

BF4 was released in terrible condition and stayed broken for ages, when did you buy it? The netcode and servers, as too seperate things were both deeply flawed and broken. Which EA admins even admitted this. But my point is why the pivot? You just said something then admittly switched to asking me to explain complex issues to you. Like no, you can google stuff yourself.
