Bug

The latency jumps to 100 and a massive lag happens that all he sudden enemies are all around me or I can't do a single damage and the game glitches and it's nothing but 100. I had to press the button more than once so the character does the action. I forgot how smooth the game was from all these bugs had been happening for me

This isn't a game bug; it's a connectivity issue.

Run WinMTR the next time this happens. There's a guide here.
