Not only harder tasks but also worse rewards... The fast condition recovery was always 10% at level 8 and very helpful, now there is only 20% at level 16, which you won't reach until around last week of the season (or not at all with these bad tasks).
Also the x2 video bonus for training was very helpful and we don't get it at all anymore... I am really thinking of not buying the sponsor anymore. It gets worse and worse every time and they always want you to spend lots of tokens for the tasks or to skip levels.
