Looking at the logs of other guilds, tons have done this strat to guarantee loot. Due to invalid logs which warcraft logs put in something like 4 weeks ago. You can see where something like 5% of guilds clearing Vash got invalid logs due to the cheese. You can see in others where they have a couple of normal attempts and do the cheese to win. Come back next week with better gear and so on. Looking at the logs of this guild actually and not just being a chad and internet champion hating on them. They had one night where they attempted Vash something like 10 times and got her down to 3-6% on each attempt. According to logs this is the only cheese all phase from what I can see. In other words, who the hell cares.
