Things that would improve PvZ2

PvZ2 is a decent game but it has a lot of problems and here is a list of them:

1°: Penny's pursuit levels are very repetitive and we haven't had new ones for a long time.

2°: It's been a while since we've seen new zombies and this makes the events very repetitive

3°: the events do not have much variety, like conveyor levels and Last Stand are never in this events.

That's basically it, I think these 3 things would improve the game's by a lot.

Thanks for the time.
