I also got addicted to WoW during quarantine while I was at home and even made some progress. However, I have used some leveling services from Cakeboost, for example, I recently bought a WoW Arena Rating 2v2 3v3 boost from them https://cakeboost.com/wow-shadowlands/service/sl-arena-rating&1195 and they quickly helped me achieve what I wanted rating at a very reasonable price. Have you ordered such a boost somewhere, how long did it take?
