I had the exact same issue finding a reliable tank for my keys at the start of the season on US servers. After days of failing with random groups, I decided to look for a wow mythic+ boost to get the loot I needed. It saved me so much frustration because I didn't have to wait for the meta to settle down. I managed to get my gear score up without spending my whole weekend shouting in chat. Now I can actually enjoy the game instead of stressing over timer failures. It’s a solid workaround if you just want to skip the headache of finding a coordinated group.
