Class 'Training Room' and game mode ideas

This is just a quick idea that I had. I think that PopCap should add several different areas where different character classes can put their abilities and weapons to the test. There could be several different sections where several abilities would come in handy. This could be useful for new players as they will learn how to use the characters. These areas can be called 'training rooms' which act as playable tutorials for each character class. Several examples of areas is that in Citron's training room, there could be a timed obstacle course which he needs to use Citron Ball for, in the Cactus' room, there could be floating gnome targets far away in the distance, testing her sniping abilities. There could also be several Zombies that can spawn in the Peashooter's room which he can use the Chili Bean Bomb for.

I also had some ideas for new game modes, too. One is a 'Last Team Standing' mode, in which each player starts with a certain number of lives (probably three or five), and must vanquish opponents. If an opponent is vanquished, they lose a life. If all lives a lost, the player is out for the rest of the game and has to spectate their teammates until the match ends. Whichever team has teammates who are still standing wins.
