I'll try to answer several questions in one post.
@kingblinks : Problem with trying to analyze game builds that contain incomplete features is that you get incomplete idea of whats there. Given all numbers in the conversion screen are server based what you see there is whatever the developer who was working on the screen placed as placeholder...
Also, and I'll say it again, there won't be boxes containing Mythicals any longer. Getting a mythical will require gameplay work, you won't be able to just buy them any more - tokens won't help here. The only way to get a mythical will be finding an item that can be transformed into one and then work your way there. Also, Mythicals have 50 items levels so even when you get one, there is still work to get to a Max Level Mythical. (This is for you @Fang456, as well)
@killymachine : We haven't touched any clan related features in the upcoming update.
@2ed : Current Mythicals are going to be far from useless. They're still going to be very strong items. There will be stronger items which are better balanced. As I told KingBlinks - there will be no way to buy mythicals so no player will be able to pay his way into mythicals.
You will of course be able to see how many, and which, transformation every item has.
@Cyborg : This update will be out mid August, which means during the coming week or the next.
All in all, everyone who has mythicals now will still have a seriously strong mech. It won't be the strongest the game has to offer any more, but this just means you now have new items to get and new battles to win to be the best. If what you looking for is staying the strongest without needing to work forever in the game, than that's unfortunate.
But if you're willing to take advantage of the new opportunities and strive even higher, and fight your way into stronger, better mechs than you could have ever before - you're going to really enjoy this!
