I'm wondering when we'll see any adjustments to Demacia as a region. It's kinda fucked right now. It basically has only one deck in constructed play because it has no control tools or reach, and its midrange now loses hard to other midrange decks like Sejuani and Heimer, so all that's left is midrange-aggro that's still inferior to other decks of that type. It's the worst region and, more importantly, the least diverse region In terms of how you can build it.
Mageseekers particularly feel like an archetype that could use some love, as could Last Breath.
Hopefully next expansion will see some more variety for Demacia.
