In general, I agree with this gripe. Especially the ewoks. But not Pao. Pao is readily available. You know where to get him. If you don't have him, you know what you have to do. But in the meantime, you will have to suffer the shortcoming.
But even the ewok and TIE reaper gripes are weak (even though I kinda agree). This game mode is intended to hold up for a long time, so we should not be able to do everything immediately. That means there will be parts we cannot complete now, but someday we will. I expect this means that there will come a time when we actually can farm these units, but that time is not now. Until then, we are handicapped.
The part I don't like is that this handicap is randomly applied, such that some guilds may be more handicapped than others. This creates an uneven playing field and generates claims of preferential treatment.
In short, these requirements are fluffy kittens.
