It's TOO SLOW now!
I think when we into Decks Mode, it will first get all deck with cards from u server.
It's sometime laggy for me. Specially when i want to replace 1-2cards, i have to back to Cards Mode and load it from ur server again.
I think when we save a deck with name, we know what we have in that named deck.
So why we not just select a deck from a list of name, and load that from local with a used cards filter.
I think this will make the Hardcore mode more quickly. and u can cut the timeout to 90-100 maybe.
Hardcore mode cost too much time for me. it need at least 5 mins to choose cards and another 3-5 mins to battle. It's too many for a mobile game i think.
If i spend 10 mins to play a battle, I think i will prefer HearthStone.
ECB is once elegant game imo, please don't make it long and slow.
