There is always a lot of discussion about the different battlegroups (i.e. groups of servers that can PVP with each other) and various claims about the different strengths of the various battlegroups. The hype about Battlegroup 9, a.k.a Bloodlust, has made it significantly more difficult to acquire our rating requirements. All of the glory seekers who transfer to Bloodlust really have made it significantly harder to acquire high ratings this season than the last. My 5v5 teams are around 250 rating lower than they were in the previous season with the same players playing.
I know people like to mention that the top players in other battlegroups have come here and have made it to the top. However, I think it's clear that the very best players that were originally in each battlegroup were pretty competitive with each other. The fact that so many have since congregated in Bloodlust have made it so that the top ratings are saturated with exceptionally good players. In turn, these top players push down the decent players' ratings (like mine).
A couple of my friends transferred to another battlegroup very recently and have been trying to get me to transfer there as well with stories about how much easier it is there. It is honestly tempting to transfer there.
I'm guessing it's technically infeasible, but Blizzard could make all battlegroups completely even if they merged all battlegroups together within the U.S. Then those of us suffering from the hype over my battlegroup will be able to achieve the same gear that people of our skill level in other battlegroups can. It would even help the problem a little if servers rotated among the various battlegroups a little bit so that the rating point pools intermingled. Perhaps have the servers shuffle battlegroups once a week?
Battlegroups are hurting the whole arena system badly unless something is done to make them even with one another.
