I reactivated my character to check out 2.0 I got some questions thought...

1- What will happened to my character? Will I loose him after the update?

2-Since I already got the game,will 2.0 be a free upgrade or I'll have to buy another game again?

3-I heard about the Imperial event,where is it located?

4-Any good place to farm for a lvl 40 conjurer?
