Love the concept, the menu navigation on thia game is probably the greatest i ve seen in a mobile game, huge companies can learn a Lot from this UI, got two batle passes so far and reached rank 16, then it gets a bit stale since it becomes a higher level units = win sort of thing but so much stuff to do that I dont mind, add new modes, clan wars etc. Incredible idea for a game, pay to win a bit towards the end, but a great game nevertheless.
