Is part of the problem one of nomenclature?
I'm talking here about the shard's names and how evocative they are. Excelsior! We know and love that word but most of us probably first encountered it through the musings of the late, great, Stan Lee who would use it to sign off his Bullpen Bulletins.
Similarly Reunion is considered to be "the EU shard" by dint of its name - and the other shards don't have such a grip on the imagination - even if they perhaps should. Everlasting sounds more like a battery than a testament to the game and Torchbearer can evoke not only the eternal flame being carried forward in time but also angry mobs with pitchforks
It's probably a bit late to do anything about it now, but maybe in an ideal world more "neutral" sounding names might have made things easier to balance loads, such as colours or animal names etc - especially if those names are selected to be less than inspiring.
But that might be self-defeating in itself.
Guess the only thing for it is to close the AE on Excelsior instead! 😎
