Server Performance Issues/Crappy Design

several times I have died to unknown damage. There won't be ANY mobs anywhere near me, then suddenly I die from some unknown damage, wasting my waystone and costing me experience. This has happened numerous times.

Likewise, there will be times where suddenly im swinging my weapon at monsters I was just hitting, and now no longer hitting anything, almost as if I am lagging, yet the monsters have NO lag and hit me without fail and kill me. During these times I'm also unable to dodge roll, and will just stand there instead of
even attempting to roll.

On top of many unhinged/imbalanced mechanics that aren't challenging, but just annoying and unfun, the end game experience has gotten to the point I want to rip every game designers' throat out. Fix this bullshit immediately
