When defending in PvP how are characters chosen?
I'm just curious how the game chooses which of your characters are used when defending in PvP? For example, in the current 1 star tournament, I have 7+ level one characters but only 4 or 5 of them are any good. If I play PvP with Iron Man, Storm & Venom but then go play some PvE and use some other characters, how does the game know which of my 7+ 1 star characters to use when defending? Does it just use the last group of characters I used in PvP?
