It Can get really long to level up as you spend most of your time doing nothing but wait as a low level player in eureka.
You get instantly killed if you do one mistake and you can lose worth of 3 Fates waiting time (almost an hour if unlucky).
You get no drop from fate, just exp, so if you want to upgrade your stuff you may have to wait some times.
I think, the lower FATE should pop more often while giving less reward
So it make lower level either find a group at their level, making the waiting time less boring for everyone too or either high level doing fate with them.
I think that Eureka FATE in general should have shorter pop time and a lowered reward, so people are constanty moving and having more fun.
