Playing season to get stash tab of cause. I don't care about "fresh start", conquests, cosmetics, rushing for leaderboards. etc..
1-70 solo is complete waste of time in this game, unless you are some crazy egocentric solo elitist of some kind, or just have free time to dump. There's no reason nor any special reward for it. Just three hours of time wasted into pointless turtle-speed levelling.
I must say i absolutely don't like powerlevelling in this game. It should not work like this. But since it exists,and it's not an exploit or a bug, i don't see a point why i am not supposed to ask my clanmates of friends to boost me. And when i get boosted i also do the same for other people.
