Unlikely to reach Level 50 Episode Pass as free to play

This is where I have reached, and you can see that I have not bought the pass. You must have missed a lot of GC feats. 

Assuming you get as far as box 43, and that you buy omicrons from the event store every time it refreshes, you are actually getting more of them now than you used to under the old crate system. If your roster is capable of finishing most GC feats, you will get better rewards over a month than you would have done in the old days.
