Before the april update it was pretty brutal. The drop rates were pretty awful. After the april update it was a lot more bearable but it still felt like a major grind. I came back to it recently at 400 and it was a lot more enjoyable although there are still some glitches in it which sucks. Like when ur transferring the aura at the stage before the war priest...you could be right next to ur teammate but it still wont transfer. Or how sometimes itll be a little laggy and u cant pick up the orb in oryxs thrown room.
