I have only done self-played. The runs themselves have been problem free. There is almost no communication with the boosters. Maybe because some of them don't speak English, but the ones I have chatted with have been clear in their communication. Again, the boosts themselves have been quick and painless and across multiple purchases I've always been delivered what I bought There are only two issues with WowVendor: the timing and the price. Even preset times seem to be rough estimates more than anything else and you have to reach out to find out when things happen. One boost in particular was only run 1 AM - 9 AM PDT, when I'm asleep/working. Thankfully, the boosters are flexible and we worked it out quickly. The other issue is price. Other reviews claim WV doesn't price match, I didn't even bother to try. As of right now a WoW Token sells for ~150,000g, which is roughly $21 for me. Time M15 Key runs are being sold for 50,000g on my server while the same run here costs $21. Just do some shopping and check out trade chat for your more common boosts.
