It is impossible to form a correct opinion based on fragments of games.
Regarding the case with 2 versions of the game:
For example, both SoD heroes and VT heroes might be open. I myself often check games that interest me in VT during the opponent's turn. Which, by the way, some people told me about (like HD-MOD was triggering).
Idk how you can watch another game while playing a tournament. Is everyone here a genius?
You need to concentrate on one, especially when there's a time limit.
