The issues İ have complaint about was fix and the game became more fun but İ am extremely dissappointed since İ have experienced the following at solo assault with airplane. the story appearing at the begining cost at least 10 seconds and it affects the effort to kill the mob at 50th level, so it has been designed to encourage ppl to purchase packs to upgrade the plane not designed for regular pppl pass over a very long time. This game is fun but it gets greedy, eventually they will lose players
