It was stated recently that only the top 0.5% of each Battlegroup will be receiving the armoured nether drakes. This seems to be a big problem for a couple of reasons.

There is no Battlegroup that is just made up of Oceanic servers.

At a high competitive end there is a notable loss from having a lower ping to the server you are playing on. It does not strike me as being especially fair. It's bad enough to be a lower populated server population in a populous battlegroup without also having to fight against this lag penalty. As it currently stands I don't expect Oceanic Teams to be properly represented based on server populations, and that's disappointing.

Why can't they just make it the top 0.5% of each server?

In case you're confused. My question is not rhetorical. I would like to see some reasons offered that make sense for why they have chosen to exclude some servers from the arena rewards like this.

who cares

RP servers don't deserve armoured netherdrakes, obviously.
