I thik there are two reasons for tanking
- lack of time, cannot be active as I want so I 'm staying
- enforce my team, gatherin extra sources for the next season

Is there any other reason of tanking ?

As I played only Diablo I & II, don't know the system.


btw I made two suggestions
- Save and load option (the last day of the season, when everything finished and starting again some new season from day one)
- a choice of the player if want to promote to the next level (or the opposite, to decalir that he don't want to promote) despite he played normally that season and finished in 1-8 position.
