Right now I'm in a Bad streak, working to enter top 100 again... lost three times to the same player since yesterday, ouch the damage is too stronk!You will hit the wall once you are near top 60. Almost everyone refreshes Arena orb daily. I've been stuck at 45-55 for 3weeks even with close to 90% winning rate.Yeah. I started in CBT day 3. I use a full limit breaken Lulu and an Isabela lv 33 and other 3 5* heroes. Only past week I limit broken my Lucille one time and today my champion (also ony one limit break).I think it's absolutely wonderful that you're able to get into top100 without a full 5* team. Did you start in beta?
It was hard at the beggining trying to win against high prestige players with full sets but I get closer to them each week.

Do you also refill for Arena Orbs?
