Disconnection and server issues, lag spikes, extreme frame stuttering

Hi just wanna say straight off that I really enjoy this game it's fun as hell, however, as the title suggests the disconnection and server issues, lag spikes and stuttering make the game unbearable at some times. I was just doing a trial of chaos and got disconnected on the 8th room and now the whole instance is reset and I just completely wasted my time..

I would like to keep enjoying the game but not if these issues persist. My 2 long time gaming buddies who got me on this game and played way more than I have both left because they kept dying during a disconnection or lag spike and were infuriated to keep losing xp due to the constant disconnection or server issues. They stopped running 6 mod maps due to it because they felt they were wasting their currency from dying constantly from the lag which is completely fair. Why run a no revive map when your almost certain your going to die to some bs disconnection or lag?

All of us are fully capable of handling all the content in the game when we don't have any of these issues and running a no revive is not a problem for our builds but the disconnection and lag issues are, I'm sure your doing what you can to fix these issues but maybe try putting more resources into this category of the game rather than trying to balance out op builds or whatever else, (i'm just speculating sorry for my blatancy) because if it persists no one will be left to make those op builds right?
