I have to side more with Afda on all of this.
Air has been strong for many wars, always top 3-4 for the last 4-5 wars I think, damn near won 1 or 2 of them. Air is one of the few elements that aether is weak against, and air gets drastically stronger as you increase the number of upgrades in war, which is why they've been near the top for a while now, and it was only a matter of time before they finally pulled off a win. I thought it would have been last war, but better late than never, I guess. And I think air would have won war whether they had sofree or not.
As far as OP cards go, dims are annoying and fractals are extremely strong. But their is no deck with either or both of those cards that each element can't make to counter it near 100% of the time. Sofree blows dims and fractals out of the water. Some elements can make counters to sofree, but some can't. And as afda has gained experince, he's optimized the build to the point where the best aether can do is 40-50% winrate. Supposedly higs has a counter, but I will have to see that after war. Anyways, any team fielding a single deck that counters most of a teams vault and has at least 50% chance against the other decks in the vault is frankly unallowable in war. I've never been an advocate for shards in war because I feared something like this would happen. I will admit that there have been some interesting decks this war that utilized shards, but I still prefer they should be banned from war. At the minimum, there needs to be heavy restrictions on them. Possibly even individualize the restrictions for each shard. Food for thought.
Now onto market prices. The reason I hate market prices is because it factors in cards that are used for all elements rather than each individual element. Aether has a couple strong cards that each element can take advantage of and use in war. As a result, aether cards are drastically overpriced for team aether. Aether could have lost every game this war, and market prices for aether would still be crazy expensive next war. I really think this needs to be abandoned.
