The award you got for the amount of points you had were crazy on the first day. I think I got like 40,000 points on the first day (got 1st place for the day) and got awards updated of 15,000 credits and free recruitment pod usages. Ended up with some 50,000 or so credit from that first day.
I think they may have changed the reward scheme after that first day, because it was insanely harder to the higher awards going forward.
It was a little annoying that you didn't get XP from the challenge levels. It was great getting short term rewards, but I felt like in the long run I was wasting time as I couldn't have been grinding tower/champion levels instead.
I considered how we'd run a comp for it, but I don't know how you could keep it fair, as the amount of times you can run challenge level per day is pretty limited unless you want to fork out gems (and potentially real money) for more Tickets. DJK Deeppockets would kick SW Freetoplay's ass.
