Wow Stops Responding

on TBC Anniversary server: Dreamscythe the game will stop responding about 20-30% of the time i do a /reload or enter any loading screen. I’ve trouble shot this to death…. I’ve tried just about every conceivable thing and nothing works… Should i just unsub? Because trouble shooting this for literally hours of my time when im just trying to relax and play a game that im paying a sub fee for is ridiculous.
