So I herd u liek ... - err excuse me, couldn't resist :PQuote:
Because I didn't read that obviously.
What I'm saying is that UDP can support Conquer's protocol. Although you're right, HoN may do their packets like that and ignore somethings (I'm fairly sure they don't keep resending chat packets each frame, but if you miss one they'll resend it - and yes, ingame chat is on the game server, as you can chatdisconnect from the chat server and still type ingame), they also do check packets they send back and forth to make sure they arrive. Any system like that could be implemented into Conquer and support the current packet/system protocol.
Seriously though, you can't compare HoN to Conquer, they simply use two different protocols (apples vs oranges?). Aside from the fact that the client has to be modified, which seems to be pretty well established as previously said by others, the real question is: What is the point of changing to UDP and essentially sort of recreating TCP? TCP works well for Conquer the way it is, and I believe that the community should be concerned about optimizing servers rather than reinventing the wheel.
