the lunge thing is just a mechanic they changed , not long after launch if memeory serves , attacks used to have to actually connect but it was too easy to run past them, so now they attacks lock on you just cant evade by distance now.
if your asking about server restarts they have recently commented on that
the isues your describing sound more like uploads from you to the server issues, seems to be an issue we see fairly regularly the game seems to have fairly high network demands (not bandwith but tick rate and packet loss tolernace)
do you have wireless or wired? VPN or or other thing affecting connection. is the connection seeing a lot of other traffic to? , does it only happen in the evening?
