Can't switch legend in training mode?

Then how can you try out all of the legends before joining a real game o.O

thats the standard thing. they definitely need to change that

Sad to say, that is how the Training works...

It would be great if EA changed this, so you could Train with all the Legends.

Or what might be really nice is to have a Training/Game Mode, where you can play with all the Legends against Bots to practice against.

Tencent recently added a Game Training Mode against Bots, but I have to admit the Bots they added in a really weak and easy to kill.
