Kingboost Review – 6+2 Mythic+10 Bundle (Piloted)

I used Kingboost for a 6+2 Mythic+10 package, so 8 runs at +10. They piloted the character and finished the whole order in a couple of hours. That was the main reason I booked it: I wanted the keys done fast instead of spending half the night in LFG.The runs were clean and efficient. No long wait after it started, no messy groups, and no wasted time between keys. Out of those 8 runs I got 4 solid upgrades. The account was also fine afterward — no issues from the piloted sessions.Communication was simple and the team just got through the keys without dragging anything out. If you want a 6+2 at Mythic+10 done quickly, piloted, and with some real loot out of it, this matched what I paid for.I’d use them again for the same kind of order.
