Legitimate question here, do you know how to spot a Premade? There is a massive flux of Premades especially during the weekly quest to get 1500 Honor from Random BGs which this week happens to be.
It’s also worth noting that some players use 3rd party addons to que sync times (this is typically more common on Horde since we have shorter que times and syncing is hard) Premades are actually more common on the Alliance side due to longer que times and less of a need to use 3rd party addons.
Some days you’ll encounter 3+ Premades in a row on a week like this with said quest up, other times it’s just the luck of the draw. Also just from having run so many BGs I have noticed it’s more common for under geared or less experienced players to be willing to dabble in PvP, on a week like this where the quest is up I always see more of those.
Though some of the evidence is anecdotal I do notice I lose more games on quest weeks, largely due to Premades or an undergeared/ inexperienced tank or healer here and there. I’ve come to expect these results on Random BG Honor Quest weeks. Typically as a Horde player I find the Horde does win more BGs and Epics on an average non Quest week.
