All right, first, I'd like to say that I'm not asking this to stole checkpoint from friends, because u Bungie can make some sort of requirements in order to acces PoE, something like "I get to to start from where I left only if I have completed the rounds before"
For example, I went up to Skolas with friend A and B and then we quit for whatever reason. I am the only one able to start from Skolas along with friend A and B, if a friend C will join me, he won't be able to start because he didn't do any rounds.
I say this because on lvl 35 it takes around 1 h to reach Skolas, and then me and other friends dont' have much time to spend on Destiny and continuing the Arena, and we have to quit and lose all our progress.
I dont' think it's fair.
Let me know what u guys think.
