I could say that there are two categories of players.
Those who already played most of the time in their mobile or tablet the new version, so for them the only new thing is the training
and those who played mostly in the pc (and maybe had the old version in the mobile or didn't use the mobile version much).
I 'm in the second category.
Those players have more negative opinion as they had to learn the new enviroment as the new training system too.
I think it was a big mistake from nordeus to release those two together.
I would start the new pc version first and later, when the oldiesget used to play that way, I would present the new training system.
